The target protein is expressed with sequence (Arg29-Met149) of human CST6 (Accession #NP_001314.1) fused with a 6×His tag at the C-terminus.\u003c\/p\u003e\n\n\u003cp\u003eAlternate Names: CST6\u003c\/p\u003e\n\n\u003cp\u003eSWISS: Q15828\u003c\/p\u003e\n\n\u003cp\u003eGeneID: 1474\u003c\/p\u003e\n\n\u003cp\u003eSpecies: Human\u003c\/p\u003e\n\n\u003cp\u003ePurity: ≥ 95 % as determined by SDS-PAGE.\u003c\/p\u003e\n\n\u003cp\u003eStorage: Store at -20℃. Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt. After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week.\u003c\/p\u003e\n\n\u003cp\u003eBackground: Cystatin E\/M encoded by the CST6 gene is a member of family 2 of the cystatin superfamily. It inhibits papain and cathepsin B, two of the cysteine proteases. Its mRNA was found in many tissues by the two groups who did initial cloning. However, its protein was found only in skin and sweat glands by a third group. In addition to being a cysteine protease inhibitor, cystatin E\/M is also a substrate for transglutaminases. It is required for viability and for correct formation of cornified layers in the epidermis and hair follicles, as ichq mice, with a null mutation in the cystatin E\/M gene, have defects in epidermal cornification and die between 5 and 12 days of age. Cystatin E\/M expression and function may not be limited to cutaneous epithelia. For example, it is found in rat brain and is induced during neuronal cell differentiation.\u003c\/p\u003e\n\n\u003cp\u003eBio-Activity: Measured by its ability to inhibit papain cleavage of a fluorogenic peptide substrate Z-FR-AMC. The IC50 value is approximately 16 nM.\u003c\/p\u003e\n\n\u003cp\u003eSource: HEK293 cells\u003c\/p\u003e\n\n\u003cp\u003eTag: C-His\u003c\/p\u003e\n\n\u003cp\u003eFormulation: Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
