Source and use of gelatin

Gelatin; alias: White gelatin, animal gelatin, silver gelatin

Gelatin is colorless or yellowish transparent sheet or coarse powder. A mixture of high molecular soluble proteins. Almost odorless, tasteless. It can expand to 5-10 times the original weight in cold water. Soluble in hot water, glycerol and acetic acid, insoluble in ethanol, ether, chloroform and other organic solvents. Gelatin is a mixture with no fixed structure and relative molecular weight, and its molecular weight ranges from tens of thousands to hundreds of thousands (< 300KD).

Source of gelatin: healthy animals, including cattle bones, cattle skins and pig skins.

Gelatin grade: according to gelatin freezing strength, according to the "Bloom" test, the higher the Bloom value, the higher the gelatin grade.

Application of gelatin（ttp://www.hnhbsj.com）:
(1) preparation of identification medium;
(2) protective colloid in turbid and colorimetric determination;
(3) coating of culture dish.
(4) 1% gelatin is often used as a blocking reagent in ELISA assay.
