propionic acid synthesis

Pierce™ AEDP (3

AEDP (3-[(2-aminoethyl)dithio]propionic acidHCl) is a cleavable amino acid that can be reacted with amine-reactive acylation agents to create amide bonds Alternatively the carbodiimide EDC can be used to conjugate AEDP to molecules containing amines or carboxylates which results in some degree of polymerization Reducing agents such as DTT and TCEP are effective for cleaving the
