Human Cathepsin S / CTSS Protein (His Tag)

Species : Human

Synonyms : CTSS,MGC3886

Host : HEK293 Cells

Purity :> 90 % as determined by SDS-PAGE

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 wavelength at 320 nm and 405 nm, respectively.
The specific activity is >300 pmoles/min/£gg
.
(Activation description: The enzyme achieves its activity under acidic pH)
