Invitrogen™ Phospho-4EBP1 (Thr36, Thr45) Monoclonal Antibody (V3NTY24), PE, eBioscience™, Invitrogen™

Mouse Monoclonal Antibody

Description: The V3NTY24 monoclonal antibody recognizes human and mouse eukaryotic translation initiation factor eIF4E-binding protein 1 (4E-BP1) when phosphorylated at threonine 37 and/or threonine 46. 4E-BP1 is a member of a family of translation repressor proteins that include 4E-BP2 and 4E-BP3. In its non-phosphorylated form, 4E-BP1 binds to the eIF4E translation initiation factor and represses cap-dependent translation. Phosphorylation of 4E-BP1 at multiple sites is necessary to disrupt this interaction and de-repress cap-dependent translation. Studies have identified several kinases that phosphorylate 4E-BP1. For instance, FRAP/mTOR phosphorylates Thr37 and Thr46, while ATM phosphorylates Ser111. Phosphorylation of 4E-BP1 at Thr37 and Thr46 is inhibited by the PI3 kinase inhibitors LY294002 and wortmannin. Applications Reported: This V3NTY24 antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This V3NTY24 antibody has been pre-titrated and tested by intracellular staining and flow cytometric analysis of stimulated normal human peripheral blood cells. This can be used at 5 μL (0.06 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test.
