Catalog# C336 Source HEK293 Description Recombinant Human Cystatin-SA is produced by our mammalian expression system in human cells. The target protein is expressed with sequence (Trp21-Ala141) of Human CST2 fused with a polyhistidine tag at the C-terminus. Names Cystatin-SA, Cystatin-2, Cystatin-S5, CST2 Accession # P09228 Formulation Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, pH 8.0 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).

Together with Cystatins S and SN, it is produced by the salivary gland and secreted largely in the submandibular/sublingual saliva. Cystatin SA inhibits Cathepsin L, but may not inhibit Cathepsins B and H. The functions of Cystatin SA are largely unknown. However, it has been suggested to play a role in the control of periodontal tissue destruction.
