Active Recombinant Mouse CTLA4 protein, hFc-tagged

• Cat.No.: CTLA4-1954M
• Product Overview: Recombinant Mouse CTLA4 protein(NP_033973.2)(Met1-Phe162), fused with hFc tag, was expressed in HEK293.

Specification

• Species: Mouse
• Source: HEK293
• Tag: Fc
• Protein Length: Met1-Phe162
• Form: Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Please refer to the specific buffer information in the hard copy of CoA.
• Bio-activity: Measured by its ability to inhibit IL-2 secretion by stimulated Jurkat human acute T cell leukemia cells. The ED50 for this effect is 0.05-0.3μg/mL when stimulated with 1 μg/mL Recombinant Human B7-1/CD80.
• Molecular Mass: The secreted recombinant mouse CTLA4/Fc is a disulfide-linked homodimeric protein. The reduced monomer comprises 368 amino acids and has a predicted molecular mass of 41 kDa. As a result of glycosylation, the apparent molecular mass of rm CTLA4/Fc monomer is approximately 53 kDa in SDS-PAGE under reducing conditions.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 95 % as determined by SDS-PAGE
• 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°C before opening to recover the entire contents.
