1.Alternative Name：ERBB3
2.Target：HER3
3.Source：Human HER3 was expressed from HEK293 with poly His at the C-terminal
4.Sequence：Ser20-Thr643
5.Protein structure:P21860His
6.Molecular Characterization:The protein has a calculated MW of 69kDa.The reducing (R) heterodimer protein migrates as 80-100 kDa due to glycosylation
7.Purity:SDS-PAGE>95%，SEC>95%
8.Reconstitution:sterile H2O
9.Endotoxin:<1EU/mg
10.Formulation:Lyophilized from 0.22 μm filtered solution in PBS, pH7.4.

11.SDS-PAGE

Determined by SDS-PAGE, the purity of the protein is greater than 95%.

12.SEC-HPLC

Determined by SEC-HPLC, the purity of the protein is greater than 95%.

12.ELISA

When Recombinant Human HER3(Ser20-Thr643)/His Protein is immobilized at 2μg/mL (100 μL/well), the concentration of Anti-Her3 [patritumab] that produces 50% of the optimal binding response is approximately 100 ng/ml.
