Glycylglycine (CAS: 556-50-3) is the dipeptide of glycine, 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 is used as a buffer for the measurement of glucose-6-phosphate dehydrogenase (G6PDH) activity and as a component of luciferase assay buffer. 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 in ion exchange chromatography. Used as a lysis buffer, running buffer and an enzymatic reaction buffer. Used in cosmetics as a moisturizer and inflammation inhibitor for skin care products.
