DESCRIPTION

• Tag: C-His
• Purity: > 92 % as determined by SDS-PAGE
• Source: HEK293 Cells
• Species: Human
• Storage: Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
• Activity: Measured by its ability to inhibit active Cathepsin L cleavage of a fluorogenic peptide substrate Z-LR-AMC (R&D Systems, Catalog # ES008). The IC50 value is <6 nM.
• Molecule: CST7
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Lead Time: 1-3 days
• Formulation: Lyophilized from sterile PBS, pH 7.4
• Molecular Mass: Cystatin F exists as a disulfide-linked homodimer. The human cystatin F monomer consists of 137 amino acids and and has a predicted molecular mass of 16.1 kDa. As a result of glycosylation, the recombinant Cystatin F migrates as an approximately 44 kDa band in SDS-PAGE under non-reduced conditions corresponding to the dimmer.
• Reconstitution: A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
• Accession Number: NP_003641.3
• Predicted N Terminal: Gly 20
