Recombinant Human CST4, His-tagged

• Cat.No.: CST4-6768H
• Product Overview: Recombinant Human CST4(27 - 146 aa) fussed with His tag at N-terminal was expressed in E. coli.

Specification

• Description: CST4 (Cystatin-S) belongs to the cystatin family. The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. This protein strongly inhibits papain and ficin, partially inhibits stem bromelain and bovine cathepsin C, but does not inhibit porcine cathepsin B or clostripain. Papain is inhibited non-competitively.
