>Human HER2 /ErbB2 (23-450) Protein, C-Fc Tag
rh HER2 / ErbB2 (23-450) Fc Chimera is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 74.5 kDa. The predicted N-terminus is Thr 23. The reducing (R) protein migrates as 95-100 kDa in SDS-PAGE due to glycosylation.
rh HER2 / ErbB2 (23-450) Fc Chimera does not contain Herceptin mAb binding domain.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5. Normally trehalose is added as protectant before lyophilization.
