Active Recombinant Human CPA2 protein, His-tagged

• Cat.No.: CPA2-3174H
• Product Overview: Active Recombinant Human CPA2 protein(NP_001859.1) (Met 1-Tyr 417) was expressed in HEK293 with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-417 aa
• Form: Lyophilized from sterile 25mM Tris, 0.15mM NaCl, pH 7.4.
• Bio-activity: Measured by its ability to cleave a colorimetric peptide substrate, N-acetyl-Phe-Thiaphe-OH, in the presence of 5,5'Dithio-bis (2-nitrobenzoic acid) (DTNB), as measured using the wavelength at 405 nm and the extinction coefficient of 13,260 M-1 cm-1. The specific activity is >4,000 pmoles/min/μg.
• Molecular Mass: The secreted recombinant human CPA2 existing as the proform consists of 412 amino acids and has a predicted molecular mass of 46 kDa also as estimated by SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: > 90 % as determined by SDS-PAGE
• Storage: Store it under sterile conditions at -20°C to -80°C upon receiving. Recommend to aliquot the protein into smaller quantities for optimal storage. Avoid repeated freeze-thaw cycles.
• Reconstitution: It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4°C before opening to recover the entire contents.
