【Strategic Cooperation】XMJ Joins Hands with Synthego to Bring Advanced CRISPR Technology Solutions

CRISPR, an acronym for "Clustered Regularly Interspaced Short Palindromic Repeats," refers to an adaptive immune mechanism found in bacteria and archaea. This system comprises Cas nucleases and guide RNAs (gRNAs) and was initially utilized by microorganisms to recognize and cleave viral DNA, thereby providing immunity against viral infections. It has since been engineered into a powerful gene-editing tool. Following the seminal discovery by Drs. Doudna and Charpentier in 2012 of the molecular mechanism underlying DNA cleavage mediated by the CRISPR-Cas9 system, extensive research and optimization efforts by the global scientific community have advanced this technology into a highly precise and broadly applicable genomic editing platform. Currently, CRISPR-based technologies are widely employed across diverse fields, including gene editing, RNA editing, base editing, molecular diagnostics, and live-cell imaging. They have enabled genetic modifications in a wide range of organisms, including humans, thereby accelerating advancements in both basic research and clinical applications. To achieve precise gene editing using CRISPR technology, the design of guide RNA (gRNA) and the selection of Cas nucleases are two critical factors. The choice of gRNA depends primarily on the specific type of genetic modification required, such as gene knockout (KO), gene knock-in (KI), base editing, prime editing, CRISPR interference (CRISPRi), or CRISPR activation (CRISPRa). Synthego offers a freely accessible CRISPR design tool available to researchers worldwide, which facilitates the design and selection of optimal gRNA sequences for targeted editing of over 120,000 genes. Furthermore, the appropriate selection of Cas enzymes is essential for experimental success. Cas9, originally derived from Streptococcus pyogenes (SpCas9), was the first widely adopted nuclease and remains the most commonly used. However, a growing range of natural and engineered Cas variants are now available for specialized applications. For example, Cas9 nickase induces single-strand breaks to enhance editing precision, while high-fidelity Cas9 variants significantly reduce off-target effects. Additionally, Cas13, a naturally occurring nuclease, demonstrates considerable potential in molecular diagnostics. In advancing the application and development of CRISPR technology, Synthego serves not only as a leading provider of integrated CRISPR solutions but also as a strategic partner committed to innovation and customer success. The company supplies all key components required for CRISPR-based gene editing, including gRNA design and synthesis services, as well as a comprehensive portfolio of natural and engineered gene editing enzymes. Its product offerings span research-grade, clinical-grade, and GMP-grade materials, supporting researchers throughout the entire pipeline—from basic research to clinical translation. Research-grade product for preclinical research and development Within Synthego's product portfolio, research-grade products hold a central position, specifically developed to support early-stage preclinical research.

Recommendation | CRISPR / Cas Systems

CRISPR and Cas proteins collectively constitute the adaptive immune system in prokaryotes and have been harnessed as highly precise molecular tools for targeted editing of DNA and RNA. The Cas9 protein (CRISPR-associated protein 9), in particular, has emerged as the cornerstone of genome editing due to its capacity to generate site-specific double-strand breaks in genomic DNA, enabling programmable and efficient genome modification. In various model organisms, these double-strand breaks are predominantly repaired through the non-homologous end joining (NHEJ) pathway, often resulting in insertions or deletions that lead to gene inactivation; alternatively, when a repair template is provided, the homologous recombination (HR) pathway facilitates precise integration of exogenous genetic sequences. In human cells, the CRISPR/Cas9 system has been rigorously validated for applications in gene knockout and gene replacement, demonstrating robust efficacy in correcting disease-causing mutations and offering a transformative approach for the treatment of monogenic disorders. As gene editing technologies continue to advance in precision, efficiency, and safety, and as their applications expand across diverse fields, Cas9-based systems exhibit substantial potential in gene therapy, agricultural biotechnology, and the development of novel biopharmaceuticals, positioning them as pivotal instruments in advancing both fundamental research and translational life sciences.

This article will focus on introducing the cost-effective substrate product series under the KPL brand that are suitable for Western blotting technology. Western Blot technology Western Blot technology is an immunoblotting technique used for detecting specific proteins, and it is one of the most popular methods in the field of immunoassays. Based on protein separation by molecular weight and specific antibody recognition, it involves separating proteins via electrophoresis, transferring them onto a solid-phase membrane, and then using specific antibodies for detection. In a Western Blot experiment, signal detection is a critical step, serving to visualize and quantify the target protein. In the past, colorimetric detection and low-sensitivity chemiluminescent detection drove the expansion of related research. However, with the continuous increase in requirements for detection sensitivity and advancements in imaging analysis systems, the design of chemiluminescent molecules has also achieved significant progress, enabling detection with higher sensitivity. In the Western Blot experimental system, high-quality substrates are crucial for achieving high sensitivity and low background signals. The chromogenic substrates and chemiluminescent substrates provided by KPL, with their excellent performance and reliable quality, have become core components of the Western Blot experimental system, helping researchers obtain more ideal experimental results. Chemiluminescence Chemiluminescence is the optimal choice for detecting trace proteins.

The luminescence intensity is significant, allowing for easy and clear capture by chemiluminescent imagers. This product is supplied as a stable two-component solution, which can be prepared for immediate use at a 1:2 ratio. It is available in three specifications, along with matching concentrated KPL wash buffers, further enhancing experimental convenience. LumiGLO®: Also provided as a two-component solution, it can be used simply by mixing equal volumes of the two components, ensuring easy operation. In Western Blot and ELISA detection, it is more sensitive than chromogenic substrates and produces lower background. The maximum luminescence intensity is achieved within 5 minutes after reaction with HRP, and the signal can persist for 1 to 2 hours. It supports multiple stripping and re-probing of immunoblot membranes, and its linear dynamic range is superior to that of most similar products. Thus, it is widely applicable to various protein detection experiments. The detection results of both products can be permanently recorded using X-ray films or chemiluminescent imagers.

Uncovering Virusys Human Herpes Virus Antibodies: A Research Tool from Laboratory to Clinic

When approximately 90% of adults worldwide carry at least one type of herpes virus (such as HSV, EBV, and CMV), tools for the accurate detection and research of these "latent pathogens" become the core competitiveness in virology research. As a brand under the LGC Group focusing on virology reagents, Virusys has established itself as a reliable partner for researchers unraveling the mysteries of herpes viruses, backed by its strong capabilities—offering over 70 highly specific monoclonal antibodies and having one-third of its products featured in academic journals.Herpes viruses are a group of enveloped double-stranded DNA viruses belonging to the Herpesviridae family. To date, more than 100 types of herpes viruses have been identified. Herpes viruses associated with human infections are referred to as Human Herpesviruses (HHV). Based on their genetic structure, homology, and related characteristics, human herpes viruses are classified into three subfamilies: Alphaherpesvirinae, Betaherpesvirinae, and Gammaherpesvirinae. Among them, HSV-1, HSV-2, and VZV belong to the Alphaherpesvirinae subfamily; HCMV, HHV-6, and HHV-7 belong to the Betaherpesvirinae subfamily; and EBV and HHV-8 belong to the Gammaherpesvirinae subfamily. These viruses can cause a variety of diseases, ranging from common oral and genital herpes to severe congenital infections and certain types of cancer. Understanding these viruses is conducive to better research on their biological characteristics, pathogenic mechanisms, and the development of corresponding therapeutic methods.

Herpes Simplex Virus (HSV)Herpes Simplex Virus (HSV) is a major pathogen that widely infects humans, mainly classified into two types: HSV-1 and HSV-2. Its infection can cause a variety of diseases, ranging from oral herpes to severe encephalitis. An in-depth understanding of the HSV life cycle is the foundation for developing effective diagnostic methods and intervention strategies.HSV infection relies on a series of key proteins, among which envelope glycoproteins (such as gD, gB, gC, gE, gG, and gH/gL) are core targets. Specifically, gD is responsible for initiating binding to host receptors and serves as the primary target of neutralizing antibodies; while gB, due to its high conservation, has become a preferred target for the development of vaccines and therapeutic antibodies. Immediate-early proteins (such as ICP0 and ICP4) act as "switches" for viral gene expression—their presence marks the onset of viral infection and represents important potential targets for antiviral drug screening.Targeting these core molecules, Virusys offers a range of validated, high-quality HSV antibodies.

Recommendation | Low Endotoxin L-Cysteine and Its Hydrochloride Salt

L-Cystine, also known as Diaminoalanine, is a sulfur-containing amino acid that exists in small amounts in proteins and is mostly found in keratin of hair, nails, etc. The structural formula of cystine is as follows:L-Cystine dihydrochloride is the stable salt form of L-cystine, and its structural formula is as follows:L-cystine itself has a very low solubility in water, but its dihydrochloride form greatly enhances water solubility, making it more convenient to use in liquid culture media and drug preparations. Therefore, the function of "L-cystine" discussed is usually realized in practical operation in the form of "L-cystine dihydrochloride". Their applications in biopharmaceuticals mainly fall into two major fields: as key additives in cell culture media and as excipients or stabilizers in drug formulations. 1. As key additive in cell culture mediaThis is the most important and core application of L-cysteine in biopharmaceuticals. ① Provide essential amino acids to support cell growthCells take L-cystine into the cell through transport proteins on their cell membranes, and then rapidly reduce L-cystine to two molecules of L-cysteine in a reducing environment. ② It regulates the REDOX balance and is a precursor for glutathione synthesisL-cysteine is the rate-limiting raw material for the synthesis of glutathione (GSH), the most important antioxidant in cells. GSH can effectively eliminate ROS, protect cells from damage, reduce apoptosis, thereby extending the culture time and increasing the yield of target proteins. ③ Promote the formation of correct disulfide bondsTherapeutic proteins, especially antibodies, rely on correct intramolecular and intermolecular disulfide bond connections for their complex structures. L-cysteine/cysteine, as a direct participant in disulfide bonds, can ensure that disulfide bonds are formed rapidly and accurately during protein synthesis and folding. 2. As an active ingredient in drug preparationsIn addition to being used as an additive in cell culture, L-cystine itself can also be used as a drug or a drug excipient. ① As a therapeutic drugHair and skin health: Cystine is an important component of keratin, which is the main structural protein of hair, skin and nails. Therefore, it is sometimes used as an ingredient in compound preparations to treat hair loss or improve skin conditions.Antioxidant therapy: As a precursor of glutathione, it can theoretically be used to enhance the body's antioxidant capacity, but it is usually used in combination with other drugs (such as B vitamins). ② As an excipient or stabilizer for drug preparationsAntioxidants: By taking advantage of its reducing property, L-cysteine can protect drug components from oxidation and degradation, thereby extending the efficacy period of the drug.Stabilizer: In some specific biopharmaceutical formulations, L-cysteine may help maintain the stability of protein drugs. 3. Advantages of L-Cystine dihydrochlorideStability: Compared with L-cystine, L-cystine dihydrochloride is more stable in both solid state and solution, less prone to moisture absorption and oxidation, and is convenient for storage and weighing.High solubility: It is easy to prepare into a high-concentration stock solution and convenient to add to the culture medium. SummaryL-cystine and L-cystine dihydrochloride are important multifunctional molecules in biopharmaceuticals. Its core value lies in serving as a key additive in cell culture media, by supporting cell growth, maintaining REDOX homeostasis and promoting correct protein folding. At the same time, it also functions as an active ingredient in drugs or an excipient in preparations in a few cases. Meanwhile, the stability and water solubility of L-cysteine dihydrochloride have drawn attention, making it a reliable and indispensable component in biopharmaceutical processes. As a long-term and fixed supplier for many well-known global medium manufacturers and pharmaceutical enterprises, PanReac AppliChem, with its outstanding product quality and strict quality control, provides reliable low-endotoxin pharmaceutical-grade L-cystine and L-cystine dihydrochloride for researchers and pharmaceutical enterprises.

Advancing purification strategies for large viral modalities using nanofiber adsorbent technology

Introduction Oncolytic viruses, like herpes simplex virus (HSV) and vaccinia virus (VACV), are gaining traction in cancer therapy due to their selective replication in tumor cells, capacity to induce cell lysis, and ability to trigger anti-tumor immune responses. Similarly, pseudotyped lentiviral vectors (LVV), such as GalV and VSV-G, enhance gene therapy by enabling cell-type-specific transduction. This can can impact downstream purification strategies. Traditional resin-based chromatography approaches face limitations in scalability, yield, and host cell protein (HCP) clearance. To address these bottlenecks, this study investigates a novel nanofiber-based adsorbent as an alternative purification strategy. This innovative platform offers promising advantages in binding capacity, impurity clearance, and process throughput, potentially transforming the downstream processing of large viral vectors. Larger viral vectors for gene therapy: LVV, HSV, and VACV Aims of study ? Evaluate purification performance of a novel nanofiber adsorbent for LVV with different pseudotyped envelopes (VSV-G, 4070A, GalV) and oncolytic virus such as HSV ? Assess host cell driven proteins and dsDNA removal to determine impurity clearance capability ? Investigate scalability potential for industrial implementation of nanofiber-based purification 1. Pseudotyped LVV production and purification workflow 2. Higher binding capacity of VSV-G LVV particles using LentiHERO® nanofiber adsorbent LentiHERO® processed large feed volumes before breakthrough of functional and physical LVV particles. 3. Maximizing the LVV recovery yield with high purity via optimized protocol 82% lentiviral recovery with yields > 2E+9 TU/mL of adsorbent and > 90% dsDNA/HCP clearance 4. Processing with LentiHERO® greatly reduces volumes for formulation at manufacturing scale ? Arginine elution eliminates the need for post-elution dilution, simplifying the process ? Low salt or arginine elution minimizes buffer consumption and reduces processing volume 5. Non-VSV-G pseudotyped LVV purification by LentiHERO®1 Lentiviruses can be pseudotyped with different envelope glycoproteins to enhance transduction efficiency and specific tropism. This impacts downstream purification strategies. ? Efficient purification of non-VSV-G lentiviral vectors (4070A: 100%, GalV: 36%) achieved ? Robust impurity reduction: >98% host cell proteins and >87% residual dsDNA without compromising vector functionality 6. Upstream-downstream workflow of oncolytic HSV-1 7. HSV purification profile on LentiHERO® using wt HSV-1(KOS) Load volume 15 mL to a screening device measured 1.5E+10 IU/mL adsorbent. Infectious HSV recovery yield was 56%, 9.2E+9 IU/mL adsorbent.
