Specifications

Clone Host Grade Applications
Monoclonal Rabbit B FC
Translation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the eIF4E translation initiation factor. Hyperphosphorylation of 4E-BP1 disrupts this interaction and results in activation of cap-dependent translation (1). Both the PI3 kinase/Akt pathway and FRAP/mTOR kinase regulate 4E-BP1 activity (2,3). Multiple 4E-BP1 residues are phosphorylated in vivo (4). While phosphorylation by FRAP/mTOR on Thr37 and Thr46 does not prevent the binding of 4E-BP1to eIF4E, it is thought to prime 4E-BP1 for subsequent phosphorylation at Ser65 and Thr70 (5).
Catalog #0004-19K
ApplicationsSuitable for use in Western Blot and Flow Cytometry. Other applications not tested.
Recommended DilutionWestern Blot: 1:1000. Incubate membrane with diluted antibody in 5% w/v BSA, 1X TBS, 0.1%
Tween-20 at 4°C with gentle shaking, overnight.
Flow Cytometry: 1:400.
Optimal dilutions to be determined by the researcher.
Storage and StabilityMay be stored at 4°C for short-term only. For long-term storage, 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.
