Recombinant Human EFNB2 protein(Met1-Ala229), His-tagged

• Cat.No.: EFNB2-3191H
• Product Overview: Recombinant Human EFNB2 (NP_004084.1) (Met 1-Ala 229) was expressed in HEK293, fused with a C-terminal polyhistidine tag.

Specification

• Species: Human
• Source: HEK293
• Tag: His
• Protein Length: 1-229 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4. 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 human EFNB2 at 2 μg/ml (100 μl/well) can bind human EphB4 with a linear range of 1.56-12.5 ng/ml.
• Molecular Mass: The recombinant human EFNB2 consists of 213 amino acids after removal of the signal peptide and predicts a molecular mass of 23.6 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EFNB2 is approximately 35-40 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 97 % 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.
