Polyclonal Rabbit Affinity Purified E B IP
Insulin exerts its effects by binding to the insulin receptor, a disulfide-linked heterotetrameric protein comprised of two alpha subunits and two beta subunits arranged in the following configuration: beta-alpha-alpha-beta. The alpha subunits each contain insulin binding sites and are entirely extracellular in localization. The beta subunits each possess an extracellular domain, a single transmembrane domain, and a cytoplasmic tyrosine kinase domain. Binding of insulin to the alpha subunits induces a conformation change in the receptor which activates the kinase domain, stimulating tyrosine autophosphorylation of the receptor and tyrosine phosphorylation of at least five different insulin receptor substrates designated IRS-1-4, and Shc. This tyrosine phosphorylation produces docking sites for proteins bearing SH2 domains, such as PI3-K, Grb-2, Nck, and Crk. While tyrosine phosphorylation of insulin receptor substrates propagates signaling from insulin, serine and threonine phosphorylation by MAPK’s, PKA, and PKC may reduce insulin signaling.
Catalog #I8700-18A
ApplicationsSuitable for use in ELISA, Western Blot and Immunoprecipitation. Other applications not tested.
Recommended DilutionELISA: 0.1-1.0ug/ml
Immunoprecipation: 3-5ug/extract from 10e7 cells
Western Blot: 0.5-2.0ug/ml
Optimal dilutions to be determined by the researcher.
Recommended Positive ControlSerum-treated mouse fibroblast (3T3) cells.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile 40-50% glycerol, aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
