-
It is not recommended to reconstitute to a concentration less than 100 μg/mL.
Dissolve the lyophilized protein in ddH2O.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles. - Buffer
- Lyophilized from a 0.2 μm filtered solution of 20 mM TrisHCl, 150 mM NaCl, pH 8.0.
- Handling Advice
- Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
- Storage
- 4 °C/-20 °C/-80 °C
- Storage Comment
-
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.

- Background
-
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.
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. - Molecular Weight
