DescriptionRabbit polyclonal to eIF4EBP1 (phospho T36)
Specificityab47365 detects endogenous levels of 4E-BP1 only when phosphorylated at threonine 36. This antibody may cross-react with 4E-BP2 and 4E-BP3 when phosphorylated at equivalent sites.
Tested applicationsSuitable for: ICC/IF, WB, IHC-P, ELISAmore details
Species reactivityReacts with: Human
Predicted to work with: Mouse, Rat
The antiserum was produced against synthesized phosphopeptide derived from human 4E-BP1 around the phosphorylation site of threonine 36 (S-T-TP-P-G).

Purification notesThe antibody was affinity-purified from rabbit antiserum by affinity chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Our Abpromise guarantee covers the use of ab47365 in the following tested applications.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
|ICC/IF||Use a concentration of 1 - 5 µg/ml.|
|WB||1/500 - 1/1000. Detects a band of approximately 20 kDa (predicted molecular weight: 13 kDa).|
|IHC-P||Use at an assay dependent concentration.|
FunctionRegulates eIF4E activity by preventing its assembly into the eIF4F complex. Mediates the regulation of protein translation by hormones, growth factors and other stimuli that signal through the MAP kinase and mTORC1 pathways.
Sequence similaritiesBelongs to the eIF4E-binding protein family.
modificationsPhosphorylated on serine and threonine residues in response to insulin, EGF and PDGF. Phosphorylation at Thr-37, Thr-46, Ser-65 and Thr-70 is regulated by mTORC1. Phosphorylated upon DNA damage, probably by ATM or ATR.

Immunohistochemical analysis of paraffin-embedded human breast carcinoma tissue using ab47365. Left image without immunising peptide treatment; right image with immunising peptide treatment.
ICC/IF image of ab47365 stained Hek293 cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab47365, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
