Active Recombinant Human EphA2 protein, His-tagged

• Cat.No.: EPHA2-2027H
• Product Overview: Recombinant Human EphA2 protein(Met1-Asn534)(P29317), fused with His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Form: Lyophilized from sterile 20mM Tris, 150mM NaCl, pH 7.5.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 Human EphA2 His at 2 μg/ml (100 μl/well) can bind Human Ephrin-A1 His & hFc, the EC50 of Human Ephrin-A1 His & hFc is 4.0-20.0 ng/mL.
• Molecular Mass: The recombinant human EPHA2 consists of 522 amino acids and predicts a molecular mass of 57.6 KDa. It migrates as an approximately 65-75 KDa band in SDS-PAGE under reducing conditions.
• Protein Length: Met1-Asn534
• Endotoxin: < 1.0 EU per μg of the 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.
