表达区间及表达系统（Source）
Rhesus macaque EGF R, Fc Tag (EGR-C5252) is expressed from human 293 cells (HEK293). It contains AA Leu 25 - Ser 645 (Accession # P55245).
Predicted N-terminus: Leu 25
蛋白结构（Molecular Characterization）
This protein carries a human IgG1 Fc tag at the C-terminus.
The protein has a calculated MW of 95.3 kDa. The protein migrates as 130-140 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素（Endotoxin）
Less than 1.0 EU per μg by the LAL method.
纯度（Purity）
>95% as determined by SDS-PAGE.
制剂（Formulation）
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5. Normally trehalose is added as protectant before lyophilization.

电泳（SDS-PAGE）
Rhesus macaque EGF R, Fc Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
活性（Bioactivity）-ELISA
Immobilized Human EGF, Tag Free (Cat. No. EGF-H4114) at 10 μg/mL (100 μL/well) can bind Rhesus macaque EGF R, Fc Tag (Cat. No. EGR-C5252) with a linear range of 39-625 μg/mL (QC tested).
Protocol
背景（Background）
The epidermal growth factor receptor (EGFR; ErbB-1; HER1 in humans) is the cell-surface receptor for members of the epidermal growth factor family (EGF-family) of extracellular protein ligands. The epidermal growth factor receptor is a member of the ErbB family of receptors, a subfamily of four closely related receptor tyrosine kinases: EGFR (ErbB-1), HER2/c-neu (ErbB-2), Her 3 (ErbB-3) and Her 4 (ErbB-4). Mutations affecting EGFR expression or activity could result in cancer.
