Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile PBS, pH 7.4.Please 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: Measured by its binding ability in a functional ELISA.Immobilized recombinant Human EFNA4h(NEW) at 10 μg/ml(100 μl/well) can bind human EPHA7-His/Biotin, The EC50 of human EPHA7-His/Biotin is 150-320 ng/mL.
• Molecular Mass: The recombinant human EFNA4 consists of 157 amino acids and predicts a molecular mass of 17.8 kDa.
• Protein Length: Met1-Gly171
• Endotoxin: < 1.0 EU per μg protein as determined by the LAL method.
• 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°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.
