• Cat.No.: CR2-4019H
• Product Overview: Recombinant Human CR2 protein(P20023-1)(Ile21-Arg971), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: Ile21-Arg971
• Tag: C-His
• Form: Supplied as 0.22μm filtered solution in PBS (pH 7.4).
• Bio-activity: Immobilized Human CD21, His Tag at 1ug/ml (100ul/Well) on the plate. Dose response curve for Anti-CD21 Antibody, hFc Tag with the EC50 of 2.9ng/ml determined by ELISA.
• Molecular Mass: The protein has a predicted MW of 105.3 kDa. Due to glycosylation, the protein migrates to 110-130 kDa based on Bis-Tris PAGE result.
