Active Recombinant Human FCGR3B protein, Biotinylated

Specification :
| Source : E. coli | Species : Human | Predicted N Terminal : Met | Form : Lyophilized from sterile PBS, pH 7.4, 5% trehalose, 5% mannitol and 0.01% Tween80. | Bio-activity : Measured by its ability to bind human IgG1 in a functional ELISA. | Molecular Mass : The recombinant human CD16b comprises 176 amino acids and has a predicted molecular mass of 20 kDa. | Endotoxin : Please contact us for more information. | Purity : > 90 % as determined by SDS-PAGE. | Characteristic : Labeling ratio of biotin to protein is 5.51. | 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 0.25 mg/ml. Centrifuge the vial at 4°C before opening to recover the entire contents. | Shipping : In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
