CST1

Alternative Names: Cystatin-1, CST1, Cystatin-SN, Cystatin-SA-I, Salivary cystatin-SA-1.

CST1, a member of the type 2 salivary cystatin family, is present in various fluids and secretions, such as plasma, tears, and saliva. The cystatin superfamily consists of proteins with multiple cystatin-like sequences. Some of these proteins inhibit cysteine protease activity, while others do not. In gastric cancer, CST1 expression is elevated in cancerous lesions compared to noncancerous areas, and there is a notable association between high CST1 expression and clinicopathological features.

Product Details

Product Description

Recombinant Human Cystatin SN is a protein molecule that belongs to the cystatin family. With a molecular weight of approximately X kDa, it plays a significant role in regulating protease activity within the body. Cystatin SN is involved in inhibiting the activity of cysteine proteases, which are enzymes responsible for breaking down proteins. This recombinant protein is produced through genetic engineering techniques, enabling its use in various research and therapeutic applications. Its precise mechanism of action and potential therapeutic implications make Recombinant Human Cystatin SN a subject of interest in the scientific community.

Product Guarantee

If your product is within its expiration period, and has not performed according to expectations, fill out the sample return form. Return the unused sample frozen, with the auto generated packing slip to the address on the instructions. You will receive a full refund along with a replacement of the unused portion (inclusive of the failed test). Damages do not cover any additional costs incurred for failed experimentation.

Storage Instruction

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

Sample Prep Instruction

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
