產品描述
The EGFR subfamily of receptor tyrosine kinases comprises four members: EGFR (also known as HER-1, ErbB1, or ErbB), ErbB2 (Neu, HER-2), ErbB3 (HER-3), and ErbB4 (HER-4). All family members are type I transmembrane glycoproteins with an extracellular ligand binding domain containing two cysteine-rich domains separated by a spacer region and a cytoplasmic domain containing a membrane-proximal tyrosine kinase domain followed by multiple tyrosine autophosphorylation sites. EGFR binds a subset of the EGF family ligands, including EGF, amphiregulin, TGF-alpha, betacellulin, epiregulin, HB-EGF, and epigen . Ligand binding induces EGFR homodimerization as well as heterodimerization with ErbB2, resulting in kinase activation, heterodimerization tyrosine phosphorylation and cell signaling. EGFR can also be recruited to form heterodimers with the ligand?activated ErbB3 or ErbB4. EGFR signaling regulates multiple biological functions including cell proliferation, differentiation, motility, and apoptosis. EGFR is overexpressed in a wide variety of tumors and is the target of several anti-cancer drugs.

別名 | ErbB; EC 2.7.10; EC 2.7.10.1; EGFR; mENA; LEGFR; ERBB; ERBB1; HER1; PIG61; NISBD2 |
Uniprot No. | P00533 |
表達區間及表達系統 | Recombinant Human EGFR/HER1 Protein is expressed from HEK293 Cells with hFc tag at the C-terminal. It contains Leu25-Ser645. |
分子量 | Approximately 95.2 kDa. Due to glycosylation, the protein migrates to 140-160 kDa based on Tris-Bis PAGE result. |
純度 | > 95% as determined by SDS-PAGE and HPLC. |
活性 | ELISA Data:Immobilized Human EGF at 2μg/ml (100μl/well) on the plate. Dose response curve for Human EGFR, hFc Tag with the EC50 of 81.0ng/ml determined by ELISA. |
內毒素 | < 1.0 EU per 1μg of the protein by the LAL method. |
制劑 | Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization. |
復溶 | Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/mL is recommended (usually we use 1 mg/mL solution for lyophilization). Dissolve the lyophilized protein in distilled water. |
