Synthetic peptide (Human) derived from a region of IRS 1 that contains serine 312.
- Phorbol ester stimulated (TPA) Chinese Hamster Ovary cell line expressing human insulin receptor (CHO-T) and transiently transfected with a plasmid encoding human IRS 1.
存放说明Shipped at 4°C. Upon delivery aliquot and store at -20°C or -80°C. Avoid repeated freeze / thaw cycles.
Preservative: 0.05% Sodium azide

纯度Immunogen affinity purified
纯化说明Purified from rabbit serum by sequential epitope-specific chromatography. The antibody has been negatively preadsorbed using a non-phosphopeptide corresponding to the site of phosphorylation to remove antibody that is reactive with non-phosphorylated IRS 1. The final product is generated by affinity chromatography using an IRS 1-derived peptide phosphorylated at serine 312.
Our Abpromise guarantee covers the use of ab4865 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

功能May mediate the control of various cellular processes by insulin. When phosphorylated by the insulin receptor binds specifically to various cellular proteins containing SH2 domains such as phosphatidylinositol 3-kinase p85 subunit or GRB2. Activates phosphatidylinositol 3-kinase when bound to the regulatory p85 subunit.
疾病相关Polymorphisms in IRS1 may be involved in the etiology of non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853].
序列相似性Contains 1 IRS-type PTB domain.
Contains 1 PH domain.
翻译后修饰Serine phosphorylation of IRS1 is a mechanism for insulin resistance. Ser-312 phosphorylation inhibits insulin action through disruption of IRS1 interaction with the insulin receptor.
Phosphorylation of Tyr-896 is required for GRB2-binding.

Peptide Competition and Phosphatase Stripping: Extracts prepared from CHO-T cells transiently transfected with wild-type human IRS 1 and treated with TPA were resolved by SDS-PAGE on a 10% polyacrylamide gel and transferred to PVDF. Membranes were treated with lambda phosphatase (1) or left untreated (2-6), blocked with a 5% BSA-TBST buffer overnight at 4oC, then incubated with 0.50
µg/mL ab4865 antibody for two hours at room temperature in a 3% BSA-TBST buffer, following prior incubation with: no peptide (1-3), the non-phosphopeptide corresponding to the immunogen (4), a generic phosphoserine containing peptide (5), or, the phosphopeptide immunogen (6). After washing, membranes were incubated with goat F(ab’)2 anti-rabbit IgG alkaline phosphatase and signals were detected using the Tropix WesternStar method. The data show that only the peptide corresponding to ab4865 blocks the antibody signal, thereby demonstrating the specificity of the anti
