Active Recombinant Human EPHA4 protein(Met1-Thr547), His&hFc-tagged

• Cat.No.: EPHA4-942H
• Product Overview: Recombinant Human EPHA4 (NP_004429.1)(Met 1-Thr 547) was expressed in HEK293, fused with the C-terminal polyhistidine-tagged Fc region of Human IgG1 at the C-terminus.

Specification

• Species: Human
• Source: HEK293
• Tag: Fc&His
• Protein Length: Met1-Thr547
• 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 EPHA5 at 20 μg/ml (100 μl/well) can bind human EFNA4-Fc with a linear range of 1.28-32 ng/ml.
• Molecular Mass: The recombinant human EPHA4/Fc chimera is a disulfide-linked homodimer. The reduced monomer consists of 776 amino acids and predictes a molecular mass of 86.5 kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh EPHA4/Fc monomer is approximately 100-110 kDa due to high levels of glycosylation.
• Endotoxin: < 1.0 EU per μg of the protein as determined by the LAL method
• Purity: > 92 % 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.
