Catalog# C335 Source HEK293 Description Recombinant Human Cystatin-S produced by transfected human cells is a secreted protein with sequence (Ser21Ala141) of Human CST4 fused with a polyhistidine tag at the C-terminus. Names Cystatin-S, Cystatin-4, Cystatin-SA-III, Salivary Acidic Protein 1, CST4 Accession # P01036 Formulation Lyophilized from a 0.2 μm filtered solution of 20mM MES, 150mM NaCl, pH 5.5 Shipping The product is shipped at ambient temperature. Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100 μg/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE. Endotoxin Less than 0.1 ng/µg (1 IEU/µg).

This protein, which is phosphorylated at both its N- and C-terminal regions, belongs to the cystatin family. Cystatin-S can function as an inhibitor to papain or ficin, it partially inhibits stem bromelain and bovine cathepsin C.
