Background

CST1 (Cystatin-SN) is a member of the type 2 salivary cystatin family found in a variety of fluids and secretions, including plasma, tears, and saliva. The cystatin superfamily encompasses proteins that contain multiple cystatin-like sequences. Some of the members are active cysteine protease inhibitors, while others have lost or perhaps never acquired this inhibitory activity. CST1 was upregulated in cancerous lesions of gastric cancer tissues compared to noncancerous regions and clinicopathological analysis showed a significant correlation between high expression of CST1. Recombinant human CST1 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

1. I notice you sell both antibodies and recombinant protein for human cystatin SN. Could you perhaps develop an ELISA for this protein?
   • NBP1-55995 and H00001469-B01P are both suitable for use as antibodies in ELISA. While a kit is not in development, you could use these to make your own ELISA kit, as many of our users do.
