Active Recombinant Human CD19 protein, His-tagged

Source :	HEK293
Species :	Human
Tag :	His
Form :	Lyophilized from sterile PBS, pH 7.4
Bio-activity :	Immobilized Human CD19 His at 2 μg/ml (100 μl/well) can bind Anti-CD19 Antibody, the EC50 of Anti-CD19 Antibody is 5-40 ng/mL.
Molecular Mass :	The recombinant human CD19 consists of 283 amino acids and predictes a molecular mass of 31.6 kDa. In SDS-PAGE under reducing conditions, rhCD19 migrates as an approximately 47 kDa band due to glycosylation.
Protein length :	Met1-Lys291
Endotoxin :	< 1.0 EU per μg of the protein as determined by the LAL method
Purity :	> 90 % 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.
