Protocol
Product Description
CST's PathScan® Phospho-4E-BP1 (Thr37/Thr46) Sandwich ELISA Antibody Pair is offered as an economical alternative to our PathScan® Phospho-4E-BP1 (Thr37/Thr46) Sandwich ELISA Kit #7216. Capture and Detection antibodies (100X stocks) and HRP-conjugated secondary antibody (1000X stock) are supplied. Sufficient reagents are supplied for 4 x 96 well ELISAs. The Phospho-4E-BP1 (Thr37/Thr46) Capture Antibody is coated in PBS overnight in a 96 well microplate. After blocking, cell lysates are added followed by a 4E-BP1 Detection Antibody and anti-Mouse IgG, HRP conjugated antibody. HRP substrate, TMB, is added for color development. The magnitude of the absorbance for this developed color is proportional to the quantity of Phospho-4E-BP1 (Thr37/Thr46) protein.
Antibodies in kit are custom formulations specific to kit.

Background
Translation repressor protein 4E-BP1 (also known as PHAS-1) inhibits cap-dependent translation by binding to the translation initiation factor eIF4E. 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 at Thr37 and Thr46 does not prevent the binding of 4E-BP1 to eIF4E, it is thought to prime 4E-BP1 for subsequent phosphorylation at Ser65 and Thr70 (5).
