EGFR (phospho-Y1148) polyclonal antibody Background :
Epidermal growth factor mediates its effects on cell growth through its interaction with a cell surface glycoprotein designated the EGF receptor. Binding of EGF or TGFα to the EGF receptor activates tyrosine-specific protein kinase activity intrinsic to the EGF receptor. The carboxy-terminal tyrosine residues on EGFR, Tyr 1068 and Tyr 1173, are the major sites of autophosphorylation, which occurs as a result of EGF binding. Once activated, EGFR mediates the binding of the phosphotyrosine binding (PTB) domain of GRB2 through direct interactions with Tyr 1068 and Tyr 1086 and through indirect interactions with Tyr 1173 in the Ras signaling pathway. Tyr 1173 of EGFR also functions as a kinase substrate. Phosphorylation of Tyr 992, Tyr 1068 and Tyr 1086 is required for conformational change in the C-terminal tail of the EGF receptorgulates Actin filament accumulation at the plasma membrane and Cdc42 stimulates formation of filopodia. Product :
Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Storage&Stability :
Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles. Specificity :
p-EGFR (Y1148) polyclonal antibody detects endogenous levels of EGFR protein only when phosphorylated at Tyr1148 (removal of the signal peptide). Immunogen :
Synthetic phosphopeptide derived from human EGFR around the phosphorylation site of Tyrosine 1148. Conjugate :
Unconjugated Modification :

Tips:
For phospho antibody, we provide phospho peptide（0.5mg) and non-phospho peptide(0.5mg).Describe :
Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.Formula:
Synthetic peptide was lyophilized with 100% acetonitrile and is supplied as a powder. Reconstitute with 0.1 ml DI water for a final concentration of 10 mg/ml.The purity is >90%,tested by HPLC and MS.
Storage:
The freeze-dried powder is more stable. For short time at 2-8°C. For long term storage store at -20°C.
