Purity: > 95% by SDS - PAGE Format: Liquid. In Phosphate Buffered Saline (pH 7.4) containing 10% glycerol. Cathepsin X/Z/P, also known as cathepsin Z/X, is a relatively new cysteine protease of the papain family. Compared to other members of the papain family, It has a short proregion and unique insertions. Acting as a carboxypeptidase, It displays a unique specificity. Recombinant mouse Cathepsin X/Z/P, fused to His-tag at C-terminus, was expressed in insect cell and purified by using conventional chromatography techniques
