| Specificity / Sensitivity | GRB2 Antibody detects endogenous levels of total GRB2 protein. |
| Source / Purification | Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to carboxy-terminal residues of human GRB2. Antibodies are purified by protein A and peptide affinity chromatography. Western Blotting
Western blot analysis of extracts from HeLa, A431, HEK293, Ramos, NIH/3T3, C6, COS, CHO and BAEC cells, using GRB2 Antibody. |
| Background | Growth factor receptor-binding protein 2 (GRB2) is a adaptor protein that is involved in RTK signal transduction. The SH2 domain of GRB2 binds to tyrosine phosphorylated proteins such as EGFR, IRS-1, Shc and Gab1 (1). The SH3 domain of GRB2 associates with Sos, which stimulates the GTP binding activity of Ras, leading to the activation of the MAP kinase and other signaling pathways. Phosphorylation of tyrosine 209 of GRB2 by Bcr-Abl and EGFR abolishes its association with Sos and negatively regulates downstream signaling (2). |

文献和实验Grb2蛋白(growth factor receptor-bound protein 2)
Grb2是生长因子受体结合蛋白2,又叫Ash蛋白。该蛋白参与细胞内各种受体激活后的下游调节。它能够直接与激活的表皮生长因子受体磷酸化的酪氨酸结合,参与EGF受体介导的信号转导,也能通过与Shc磷酸化的酪氨酸结合间接参与由胰岛素受体介导的信号转导。Grb2能够同时与Shc、Sos结合形成Shc-Grb2-Sos复合物,并将Sos激活，激活的Sos与质膜上的Ras蛋白结合，并将其激活,引起信号级联反应。Grb2蛋白含有一个SH2结构域和两个SH3结构域,属SH蛋白。
Generation of Antibody Molecules Through Antibody Engineering

The importance of antibody molecules was first recognized in the 1890s, when it was shown that immunity to tetanus and diphtheria was caused by antibodies against the bacterial exotoxins (1 ). Around the same time, it was shown that antisera
