Active Recombinant Human EFNA1 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. Please refer to the specific buffer information in the hard copy of CoA. | Bio-activity : Immobilized Ephrin-A1 Protein, Human, Recombinant (hFc Tag)(Cat:10882-H02H) at 2 μg/mL (100 μL/well) can bind EphA2 Protein, Mouse, Recombinant (His Tag)(Cat:50586-M08H), the EC50 is 13-64 ng/mL. | Molecular Mass : The recombinant human EFNA1 consists of 402 amino acids and predicts a molecular mass of 46.08 kDa. | Protein Length : Met1-Ser182 | 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.
