Active Recombinant Human GZMB, His tagged

• Cat.No.: GZMB-296H
• Product Overview: Recombinant Human GZMB proform (NP_004122.1) (Met 1-Tyr 247), fused with a C-terminal polyhistidine tag, was produced in HEK293 Cells.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4.
  Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
• Bio-activity: Measured by its ability to cleave a peptide substrate, tButyloxycaronylAlaAlaAspThioBenzylester (BocAADSBzl),in the presence of 5,5’Dithiobis (2nitrobenzoic acid) (DTNB). The specific activity is >1500 pmol/min/μg. (The enzyme needs to be activated by Recombinant Mouse Active Cathepsin C)
• Molecular Mass: The recombinant human Granzyme B consists of 240 amino acids and has a calculated molecular mass of 27.2 kDa. As a result of glycosylation, the apparent molecular mass of rhGranzyme B is approximately 35-40 kDa in SDS-PAGE under reducing conditions.
• Protein Length: Met 1-Tyr 247
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• Purity: ≥ 97 % as determined by SDS-PAGE ≥ 95 % as determined by SEC-HPLC.
• Storage: Samples are stable for up to twelve months from date of receipt at -20°C to -80°C
  Store it under sterile conditions at -20°C to -80°C. It is recommended that the protein be aliquoted 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℃ before opening to recover the entire contents.
