CST9

Alternative Names: Cystatin-like molecule, cystatin-9 (testatin), CLM.

CST9 belongs to the CRES subfamily within the family 2 cystatins of the cystatin superfamily. While some members of this subfamily act as cysteine protease inhibitors, CST9 may not have this inhibitory function. It is involved in hematopoietic differentiation and inflammation, and is found in the heart, placenta, lung, liver, skeletal muscle, and pancreas. The expression of CST9 is increased by LPS in various cancer cell lines, including promyelocytic leukemia (HL-60) and myelomonocytic leukemia.

Product Description

Recombinant Human Cystatin 9 is a protein that belongs to the cystatin family, a group of cysteine protease inhibitors. With a molecular weight of approximately X kilodaltons, this protein plays a significant role in regulating protease activity, thereby modulating various physiological processes. As a member of the cystatin family, Recombinant Human Cystatin 9 exhibits a unique ability to bind and inhibit specific cysteine proteases, contributing to the maintenance of proteostasis and cellular homeostasis. Its precise functions and interactions are subjects of ongoing scientific research, aiming to unravel its potential implications in various biological systems.

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
