Ficin, from Fig Tree Latex

Cat No:PDE-0017

Description

Ficin is classified as a thiol protease. It contains an active cysteine at the active site. The amino acid homology of the active site was similar to that of papain. Ficin will cut proteins on the carboxyl side of Gly, Ser, Thr, Met, Lys, Arg, Tyr, Ala, Asn and Val. The Km of the reported color developing substrate pglu-PH-Leu-p-nitroaniline is 0.43 mM. Ficin is inhibited by iodoacetamide, iodoacetic acid, N-ethyl maleimide, mercury chloride, DFP(diisopropyl fluorophosphate), TLCK (na - to Toyl-lysine chloromethyl ketone), and TPCK (N-Toyl-l-phenylalanine chloromethyl ketone). Ficin can be used to generate high-yielding F (ab ')2 fragments from mouse IgG1.
