应用备注
Western Blot: 0.5 μg/mL for HRPO/ECL detection. Recommended buffer: Casein/Tween 20 based blocking and blot incubation buffer. Usecelllysate delivered with this product as positive control: see protocol below! Immunoprecipitation (use at 1-10 μg per 10^6 vanadate-treated A431 cells). Immunocytochemistry (use at 1-10 μg/mL). Immunohistochemistry on Frozen and Paraffin Embedded Material. ELISA (use at 0.05 μg/mL). Other applications not tested. Optimal dilutions are dependent on conditions and should be determined by the user.
实验流程
Positive Control cell lysate provided: HepG2 Pervanadate Treated-recommended for ImmunoblottingFormulation: Lyophilized cell lysate from HepG2 cells. Serum starved cells were treated for 15 min. withpervanadate. Restore by addition of 200 µl H2O. After complete solubilization add 200 µl 2x SDS-PAGEsample buffer, mix and incubate at 90°C for 5 min. Store in aliquots at -20°C. Avoid repeated freezing and thawing. Application: 20 µl of positive cell lysate correspond to ca. 80. 000 cells. Use 20 µl / lane (mini gel) for HRPO/ECL detection of the target proteins. Please note: The lyophilized cell lysate contains SDS and is not recommended for applications withnative proteins such as immunoprecipitation !

EGFR/erbB receptors are activated upon binding of EGF and EGF-related growth factors such as TGF alpha, beta-cellulin, Hb-EGF, HRG, or NRG. Binding of these ligands leads to receptor homo- and heterodimerization followed by autophosphorylation and activation of downstream signal transduction pathways (MAPK, PI3K/PKB, and STAT). In addition, EGFR becomes fully activated after phosphorylation of Y869 by src family kinases. Phosphorylation of Y1069 leads to association with cbl and subsequent receptor degradation. Phosphorylation of S1071 by CamKinase II leads to attenuation of kinase activity, phosphorylation of T678 (by PKC) and T693 (by MAPK, p38) interferes with receptor endocytosis/recycling.Synonyms: EGF Receptor, Epidermal growth factor receptor, Proto-oncogene c-ErbB-1, Receptor tyrosine-protein kinase erbB-1, c-ErbB-1, erbB-1
