Cathepsin S (CTSS), recombinant human protein is supplied in frozen format. It is suitable for use in protein studies such as enzymetic analysis and protein-protein interactions. In general, recombinant proteins can also be used as an immunogen, as a protein standard, or in cell biology research applications.

This recombinant protein was expressed from a DNA sequence encoding the pro form of human CTSS (NP_004070.3) (Met 1-Ile 331) fused to a carboxy-terminal polyhistidine tag.

Activity: Measured by its ability to cleave a fluorogenic peptide substrate, (7-methoxycoumarin-4-yl) acetyl-Arg-Pro-Lys-Pro-Val-Glu-Nva-Trp-Arg-Lys (2, 4-dinitrophenyl)-NH2 (R&D Systems, Catalog#ES002). Cleavage of ES002 can be measured using excitation and emission wavelengths at 320 nm and 405 nm, respectively. The specific activity is >300 pmoles/min/µg.

Formulation: 12.5 mM MES, 0.075 M NaCl, 10% glycerol, pH 6.5.

Reconstitution: No reconstitution needed. Store at -80°C. Avoid repeated freeze-thaw cycles.

Expiration Date: Expires one year from date of receipt when stored as instructed.
