Active Recombinant Human ERBB3(Met1-Thr643), His-tagged

• Cat.No.: ERBB3-209H
• Product Overview: Active Recombinant Human ERBB3(Met1-Thr643)(P21860), fused with C-terminal His tag, was expressed in HEK293.

Specification

• Source: HEK293
• Species: Human
• Tag: His
• Protein length: 1-643 a.a.
• Form: Lyophilized from sterile PBS, pH 7.4
• Bio-activity: 1. Measured by its binding ability in a functional ELISA. 2. Immobilized human ErbB3 at 2 μg/mL (100 μl/well) can bind human NRG1 (isoform Beta1), The EC50 of human NRG1 (isoform Beta1) is 0.43 μg/mL.
• Molecular Mass: The recombinant human ErbB3 protein consists of 635 amino acids after the removal of signal peptide and has a calculated molecular mass of 70.2 kDa. As a result of glycosylation, the recombinant ErbB3 migrates as an approximately 100-110 kDa band 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. ≥ 95 % as determined by SEC-HPLC.
• 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.
