Product Description

Recombinant Human Cystatin 4, sf9 is a protein that belongs to the cystatin family. This protein is produced through recombinant DNA technology and is commonly used in scientific research and biotechnological applications. With a molecular weight of approximately [insert weight], it plays a significant role in inhibiting cysteine proteases, thereby regulating various cellular processes. Recombinant Human Cystatin 4, sf9 is a valuable tool for studying protein-protein interactions and understanding the intricate mechanisms involved in protease inhibition.

Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Avoid multiple freeze-thaw cycles.

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
