Application:
Glycylglycine (Gly-Gly) (CAS: 556-50-3) is the dipeptide of glycine, a non-essential amino acid, used in biochemical research. It is the simplest of all dipeptides and is used as a starting template for preparation of more complex peptides. Glycylglycine, a zwitterionic biological buffer often used in biological and biochemical research, and also as a part of cosmetic formulations. Uses of Glycylglycine Buffer: Glycylglycine is a dipeptide also used as a buffering agent in enzymatic assays and in medical procedures. Used as a lysis buffer, running buffer and an enzymatic reaction buffer. Used in ion exchange chromatography. It is also employed as a practical buffer with a buffering range of 7.5 - 8.9 (at 25°C). Valuable agent for experiments investigating peptide transport and absorption. The application of Glycylglycine in products 1. Food: dairy food, meat food, baked food, pasta food, flavored food, etc. 2. Medicine: health food, fillers, medical raw materials, etc. 3. Industrial manufacturing: oil industry, manufacturing industry, agricultural products, batteries, precision castings, etc. 4. Tobacco products: can replace glycerin for tobacco fragrance, antifreeze moisturizer. 5. Cosmetics: facial cleanser, beauty cream, toner, shampoo, facial mask, etc. Used in cosmetics as a moisturizer and inflammation inhibitor for skin care products. 6. Feed: canned pet, animal feed, aquatic feed, vitamin feed, veterinary medicine products, etc.Package & Storage:
Package: Bottle, Aluminium foil bag, 25kg/Cardboard Drum, or according to customer's requirement. Storage Condition: Store in sealed containers at cool and dry place; Protect from light and moisture.
