STJP002680

Current Stock:
Host: HEK293 cells
Reactivity: Human
Note: STRICTLY FOR FURTHER SCIENTIFIC RESEARCH USE ONLY (RUO). MUST NOT TO BE USED IN DIAGNOSTIC OR THERAPEUTIC APPLICATIONS.
Short Description: Recombinant-Human Cystatin-S/CST4-C-His protein was developed from hek293 cells and has a target region of C-His. For use in research applications.
Formulation: Lyophilized from a 0.22 Mu m filtered solution of PBS, pH 7.4.
Storage Instruction: Store at-20°C for up to 1 year from the date of receipt, and avoid repeat freeze-thaw cycles.
Immunoreactivity: Measured by its ability to inhibit active Cathepsin L cleavage of a fluorogenic peptide substrate Z-LR-AMC. The IC50 value approximately is 26.3 nM.
Gene Symbol: CST4
Gene ID: 1472
Uniprot ID: CYTS_HUMAN
Immunogen Region: Ser21-Ala141
Immunogen: Recombinant Human Cystatin-S/CST4 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Ser21-Ala141) of human Cystatin S (Accession #NP_001890.1) fused with a 6×His tag at the C-terminus.
Post Translational Modifications Phosphorylated at both its N- and C-terminal regions.
Function 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.
