Active Recombinant Human EFNA3 protein, hFc-tagged

Specification :
| Source : HEK293 | Species : Human | Tag : hFc | 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. | Bio-activity : Measured by its binding ability in a functional ELISA. Immobilized mouse EphA6 at 1 μg/ml (100 μl/well) can bind human EphrinA3 / Fc Chimera. The EC50 of human EphrinA3 is 299.2 ng/mL. | Molecular Mass : The recombinant human EphrinA3/Fc is a disulfide-linked homodimer after removal of the signal peptide. The reduced monomer consists of 429 amino acids and has a predicted molecular mass of 48 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rhEphrinA3/Fc monomer is approximately 60-65 kDa due to glycosylation. | Protein Length : Met1-Ser213 | Endotoxin : | 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°CStore 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.
