Active Recombinant Human EFNB2, Fc-His tagged

• Cat.No.: EFNB2-2240H
• Product Overview: Recombinant Human EFNB2 (NP_004084.1) extracellular domain (Met 1-Ala 229), fused with the polyhistidine-tagged Fc region of human IgG1 at the C-terminus, was produced in Human Cell.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc
• Protein Length: Met 1-Ala 229
• Form: Lyophilized from sterile 50 mM Tris, pH 8.0.
  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 EphB4-his at 2 μg/ml (100 μl/well) can bind human EphrinB2 Fc chimera with a linear range of 1-25 ng/ml . Immobilized human EphB4 at 2 μg/ml (100 μl/well) can bind human EphrinB2 Fc chimera with a linear range of 1-125 ng/ml.
• Molecular Mass: The recombinant human EFNB2/Fc chimera is a disulfide-linked homodimeric protein. The reduced monomer consists of 450 amino acids and predicts a molecular mass of 50.3 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EFNB2/Fc monomer is approximately 62 kDa due to glycosylation.
• Endotoxin: < 1.0 EU per μg 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℃ before opening to recover the entire contents.
