Orange G

Orange G or orange gelb is a synthetic azo dye used in histology in many staining formulations. It usually comes as a disodium salt. It has the appearance of orange crystals or powder.

Staining

The main use of Orange G is in the OG-6 Papanicolaou stain, to stain keratin, however it is also a major component of the Alexander test for pollen staining.

It is often combined with other yellow dyes and used to stain erythrocytes in the trichrome methods.

Color marker

Orange G can be used as a color marker to monitor the process of agarose gel electrophoresis, running approximately at the size of a 50 Base pair (bp) DNA molecule, and polyacrylamide gel electrophoresis. Bromophenol blue and xylene cyanol can also be used for this purpose. (However, the apparent "size" of all these dyes varies according to the concentration of agarose in the gel and the buffer system used, so one should look up the appropriate reference before using the dyes to determine how far a gel has run.)

pH indicator

Despite its two ionizable groups, it shows only two colors in aqueous solution, brilliant orange in neutral and acidic pH or red in pH greater than 9.

Orange (song)

"Orange" is a song performed by Irish comedian David O'Doherty. It was released on CD in February 2007 as part of his attempts to have a "Minor" hit single, preferably at #27 in the charts. The exploits of O'Doherty trying to have this "hit" was featured in an episode of his TV series, The Modest Adventures of David O'Doherty.

The song was written and recorded by David O'Doherty, and was recorded onto standard CD-R discs using his own laptop to do so. His phone number was written on the back of the single's (also homemade) artwork so that if the people who bought it couldn't get it to play, they could contact him and he would play them the song over the phone.

Song promotion

Less than 312 singles were produced, as it usually only takes this number of single sales to enter the Irish Single Chart top 30. As such, the physical single is now a rare collector's item for fans of his.

The song received limited airplay on the radio due to profanity in the lyrics towards the end of the song. However, O'Doherty showed up to various radio stations, such as Rick O'Shea's 2FM show, to perform a version of the single live in order to promote it.

The Annoying Orange

The Annoying Orange is an American comedy web series created by former Minnesota film student and MTV production assistant Dane Boedigheimer in 2009. It stars its creator as an anthropomorphic orange who annoys other fruits, vegetables, and various other objects by using jokes, which are sometimes crude-humored. The YouTube channel "Annoying Orange" has over almost 5 million subscribers.

Despite the show's negative critical reception, the show's popularity after its first episode led it to become the subject of a TV series, a video game, a range of toys, backpacks, couches, pillows, blankets, lunchboxes, drink bottles, mattresses, towels and a T-shirt line. Other accessories, such as costumes of the series characters, have also appeared on the market for the company.

Plot

The show is centered on Orange (voiced by Dane Boedigheimer), who resides on a fruit cart display in a kitchen with other objects such as his best friend, Pear, a Bartlett pear (also voiced by Boedigheimer). Other fruits include Passion, a (female) passion fruit played by iJustine, a grapefruit (voiced by Robert Jennings), a tiny apple known as Midget Apple (though he prefers the name Little Apple), a small marshmallow, and an elderly lemon named Grandpa Lemon, all of whom were not main characters until later episodes. Most episodes consist of Orange heckling other characters until they meet a sudden and gruesome end, usually by evisceration with a chef's knife (although the implements used to cut them up range from a blender to a toy pinwheel). Usually, Orange tries to "warn" them before it happens, blurting out the weapon-in-use, such as "Knife!"
