CST, 40223SF, Phospho-IGF-I Receptor beta (Tyr1131)/Insulin Receptor beta (Tyr1146) (D6D5L) Rabbit Monoclonal Antibody (BSA and Azide Free)

Monoclonal Antibody for studying IGF1R (Tyr1161) phosphate. Validated for Western Blotting,ELISA+. Highly specific and rigorously validated in-house, Phospho-IGF-I Receptor beta (Tyr1131)/Insulin Receptor beta (Tyr1146) (D6D5L) Rabbit Monoclonal Antibody (BSA and Azide Free) (CST #40223) is ready to ship. Product Usage Information This product is the carrier free version of product #80732. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol. This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us . Optimal dilutions/concentrations should be determined by the end user. BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity. Formulation Supplied in 1X PBS (10 mM Na 2 HPO 4 , 3 mM KCl, 2 mM KH 2 PO 4 , and 140 mM NaCl (pH 7.8)). BSA and Azide Free. For standard formulation of this product see product # 80732 Storage Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance. Specificity / Sensitivity Phospho-IGF-I Receptor beta (Tyr1131)/Insulin Receptor beta (Tyr1146) (D6D5L) Rabbit Monoclonal Antibody (BSA and Azide Free) recognizes endogenous levels of IGF-I receptor β protein only when phosphorylated at Tyr1131 and/or insulin receptor β protein only when phosphorylated at Tyr1146. This antibody cross-reacts with activated ErbB2 and ALK. Species Reactivity: Human Source / Purification Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Tyr1131 of human IGF-I receptor protein. Background 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 at Tyr1146 and either Tyr1150 or Tyr1151, while full kinase activation requires triple tyrosine phosphorylation (8).
