Overview
Papain is a cysteine protease of the papain family. It is a single chain protein. The molecular weight of papain is 23 kDa. Papain is composed of two structural domains and a cleft between them, which consists of the active site.
Application:Papain has been used in the digestion of various brain cells.
Use Papain for the complete proteolytic cleavage of proteins, limited hydrolysis of native immunoglobulins, and tissue dissociation (together with collagenase, esterase, and trypsin). The enzyme solubilizes integral membrane proteins and produces glycopeptides from purified proteoglycans. The addition of cysteine (approximately 0.5% [w/v]) is essential for enzyme activity.
