Recombinant Human CR2 protein, His-tagged

Source :	HEK293
Species :	Human
Tag :	C-His
Protein length :	Ile21-Arg971
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.
Endotoxin :	Less than 1EU per μg by the LAL method.
Purity :	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Storage :	Valid for 12 months from date of receipt when stored at -80°C. Recommend to aliquot the protein into smaller quantities for optimal storage. Please do not 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.
