Cystatin SA/CST2 Protein(C-6His) (recombinant human)

Protein Construction: Recombinant Human Cystatin SA is produced by our Mammalian expression system and the target gene encoding Trp21-Ala141 is expressed with a 6His tag at the C-terminus. Sequence: Trp21-Ala141. Fusion tag: C-6His Endotoxin: < 1.0 EU per µg as determined by the LAL method. Apparent Molecular Mass: 16 kDa. Protein function: Cystatin SA is a member of family 2 of the Cystatin superfamily. 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. Protein function: Thiol protease inhibitor. [The UniProt Consortium]
