GRB2 monoclonal antibody Background :
Growth factor receptor bound protein 2 (GRB2), also known as Ash protein, is a 24 kDa protein that contains a central Src homology (SH2) domain flanked by two SH3 domains. GRB2 is believed to be a regulatory subunit of signaling molecules whose activity is modulated by receptor binding. GRB2 associates with activated (tyrosine phosphorylated) EGFR and PDGFR via its SH2 domain as well as IRS1, SHC, and LNK through SH2 and SH3 domains. The SH3 domain binds to SOS, a guanine nucleotide exchange factor for Ras proteins. Endocytosis of activated EGFR requires the interaction of GRB2 with the GTP binding protein dynamin, a factor essential to the formation of endocytotic vesicle. It is ubiquitously expressed and several isoforms are produced by alternative splicing. On SDS PAGE, GRB2 has an apparent molecular weight of 28 kDa. Product :
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 :
This antibody detects endogenous levels of GRB2 and does not cross-react with related proteins Immunogen :
Recombinant full length Human GRB2. Conjugate :
Unconjugated Modification :
Unmodification

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.
