Active Recombinant Canine EFNB2 protein(Met1-Ala229), hFc-tagged

• Cat.No.: EFNB2-297C
• Product Overview: Recombinant Canine EFNB2 (B0LDS6) (Met1-Ala229) was expressed in HEK293 with the Fc region of Human IgG1 at the C-terminus.

Specification

• Species: Canine
• Source: HEK293
• Tag: Fc
• Protein Length: Met1-Ala229
• 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: 1. Measured by its binding ability in a functional ELISA. 2. Immobilized human EphB4-His at 10μg/mL (100μL/well) can bind Canine EFNB2-Fc3.The EC50 of Canine EFNB2-Fc3 is 25.8-60.2 ng/mL.
• Molecular Mass: The recombinant Canine EFNB2/Fc is a disulfide-linked homodimer. The reduced monomer comprises 443 amino acids and has a predicted molecular mass of 49.2 kDa. The apparent molecular mass of the protein is approximately 58 and 35 kDa in SDS-PAGE under reducing conditions.
• 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.
