CST2, Cystatin-2, Cystatin-SA, Cystatin-S5


Recombinant Human CST2 /Cystatin-SA Protein (rhCST2 / Cystatin-SA) Trp 21 - Ala 141 (Accession # AAH62679) was produced in human 293 cells (HEK293) at ACRObiosystems.

Molecular Characterization

rhCST2 / Cystatin-SA, fused with 6×His tag at the C-terminus, has a calculated MW of 15.2 kDa. The predicted N-terminus is Trp 21. DTT-reduced Protein migrates as 15-17 kDa.


Less than 1.0 EU per μg of the rhCST2 / Cystatin-SA by the LAL method.


>95% as determined by SDS-PAGE.


Lyophilized from 0.22 μm filtered solution in 25 mM Tris and 150 mM NaCl, pH 8.0. Normally Mannitol or Trehalose are added as protectants before lyophilization.

See Certificate of Analysis for details of reconstitution instruction and specific concentration.


Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).



Recombinant Human CST2 /Cystatin-SA Protein
The purity of rhCST2 / Cystatin-SA was determined by DTT-reduced (+) SDS-PAGE and staining overnight with Coomassie Blue.


Cystatin-2 (CST2) is also known as Cystatin-SA, Cystatin-S5, is a secreted thiol protease inhibitor, which belongs to the cystatin family. The type 2 cystatin proteins are a class of cysteine proteinase inhibitors found in a variety of human fluids and secretions, where they appear to provide protective functions. The CST1, CST2, CST4, and CST5 are expressed in differential, tissue-specific patterns. CST2 is expressed in submandibular and sublingual saliva but not in parotid saliva (at protein level) and is also expressed in submandibular gland and parotid gland.
