Active Recombinant Human CTSZ Protein, His-tagged

• Cat.No.: CTSZ-191H
• Product Overview: Active Recombinant Human CTSZ Protein(Q9UBR2) (Met 1-Val 303) was expressed in HEK293, fused with a polyhistidine tag at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-303 aa
• Form: Lyophilized from sterile PBS, pH 7.4.
• Bio-activity: Measured by its ability to cleave the fluorogenic peptide substrate, Mca-RPPGFSAFK (Dnp)-OH. The specific activity is >800 pmoles/min/μg.
• Molecular Mass: The secreted recombinant human CTSZ (pro form) consists of 291 amino acids and has a predicted molecular mass of 33 kDa. The apparent molecular mass of rhCTSZ is approximately 40 kDa in SDS-PAGE under reducing conditions due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method.
• Purity: > 97 % 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.
