SKU:: 0004-18
Purity:: Purified by protein A and peptide affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Synthetic peptide corresponding to residues surrounding Ser112 of human 4E-BP1. MW of Antigen: 15-20kD.
Format:: Supplied as a liquid in 10mM sodium HEPES, pH 7.5, 150mM sodium chloride, 0.1mg/ml BSA, 50% glycerol.
Extra Details:: 4E-BP1 (also known as PHAS-1) normally binds eIF4E, inhibiting cap-dependent translation. Hyperphosphorylation of 4E-BP1 disrupts this binding, activating cap-dependent translation (1). The PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 (2,3). 4E-BP1 is phosphorylated in vivo on multiple residues (4); phosphorylation by FRAP/mTOR on Thr37 and Thr46 of human 4E-BP1 may prime it for subsequent phosphorylation at sites including Ser65 and Thr70 (5). Applications: Suitable for use in Immunoprecipitation and Western Blot. Other applications not tested. Recommended Dilution: Western Blot: 1:1000 Immunoprecipitation: 1:50 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
