Specification

• Source: E. coli
• Species: E. coli
• Tag: His
• Predicted N Terminal: Ala21
• Form: Lyophilized from a 0.2 µm filtered solution in Tris and NaCl.
• Bio-activity: Measured by its ability to inhibit trypsin cleavage of a fluorogenic peptide substrate, Mca-RPKPVE-Nval-WRK(Dnp)-NH2.The IC50 value is <1.0 nM, as measured under the described conditions.
• Molecular Mass: Recombinant E. coli eco, His-tagged has a calculated MW of 17 kDa. In SDS-PAGE migrates as 18 kDa, reducing conditions.
• Protein length: Ala21-Arg162
• Purity: >95%, by SDS-PAGE under reducing conditions and visualized by silver stain.
• Storage: Avoid repeated freeze-thaw cycles. No activity loss was observed after storage at: In lyophilized state for 1 year (4ºC); After reconstitution under sterile conditions for 3 months (-70ºC).
• Reconstitution: Reconstitute at 250 µg/mL in sterile PBS containing at least 0.1% human or bovine serum albumin.
