Glycylglycine is used as a starting template for the preparation of more complex peptides. It is a substrate for the enzyme glycylglycine dipeptidase. It is also utilised as a buffer in biochemistry. Glycylglycine has been utilised in the purification and characterisation of a fructose-6-phosphate aldolase from E. coli, and in the characterisation of a PMA hydrolase from a strain of Comamonas acidovorans. The use of Glycylglycine in a [35S]GTPγ S binding assay for measuring functional coupling of G proteins with receptors has been reported.

Typical Working Concentration: 10 to 20 mM

Soluble in water (10% w/v - clear, colourless solution).
