概述
描述
CST''s PathScan® Phospho-IGF-I Receptor β (Tyr1131) Sandwich ELISA Antibody Pair is being offered as an economical alternative to our PathScan® Phospho-IGF-I Receptor β (Tyr1131) Sandwich ELISA Kit #7302. Capture and detection antibodies (100X stocks) and HRP-linked secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The phospho-IGF-I receptor β (Tyr1131) capture antibody is coated on a 96 well microplate in PBS overnight. After blocking, cell lysates are added followed by an IGF-I receptor detection antibody and anti-mouse IgG, HRP-linked antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of phospho-IGF-I receptor β (Tyr1131) protein.

背景
Type I insulin-like growth factor receptor (IGF-IR) is a transmembrane receptor tyrosine kinase that is widely expressed in many cell lines and cell types within fetal and postnatal tissues (1-3). Receptor autophosphorylation follows binding of the IGF-I and IGF-II ligands. Three tyrosine residues within the kinase domain (Tyr1131, Tyr1135, and Tyr1136) are the earliest major autophosphorylation sites (4). Phosphorylation of these three tyrosine residues is necessary for kinase activation (5,6). Insulin receptors (IRs) share significant structural and functional similarity with IGF-I receptors, including the presence of an equivalent tyrosine cluster (Tyr1146/1150/1151) within the kinase domain activation loop. Tyrosine autophosphorylation of IRs is one of the earliest cellular responses to insulin stimulation (7). Autophosphorylation begins with phosphorylation of Tyr1146 and either Tyr1150 or Tyr1151, while full kinase activation requires triple tyrosine phosphorylation (8).

The relationship between protein concentration of lysates from untreated or IGF-I-treated MCF-7 cells and the absorbance at 450 nm using PathScan® Phospho-IGF-I Receptor β (Tyr1131) Sandwich ELISA Antibody Pair is shown. Cells were serum starved overnight, treated with 100 nm IGF-I at 37°C for 5 minutes, and then lysed.
