||Full length native Human Cathepsin S purified from Human Spleen; amino acids 115-331, 217 amino acids, MWt 24 kDa.
||The protein encoded by this gene, a member of the peptidase C1 family, is a lysosomal cysteine proteinase that may participate in the degradation of antigenic proteins to peptides for presentation on MHC class II molecules. The encoded protein can function as an elastase over a broad pH range in alveolar macrophages. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene.
||Activity: Cathepsin S activity detected using Z-Val-Val-Arg-AMC
||>95% by SDS-PAGE
||Preservative: NoneConstituents: 100mM Sodium acetate, 1mM EDTA, pH 5.5
||Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
