Immunocytochemistry/ Immunofluorescence - Anti-eIF4E (phospho S209) antibody [EP2151Y] (AB76256)
Immunocytochemistry/Immunofluorescence analysis of serum starved HEK293 cells treated with CGP 57380 ab120365) labelling eIF4E (phospho S209) with unpurified ab32124 at 1/100. Decrease in eIF4E (phospho S209) expression correlates with increased concentration of CGP 57380, as described in literature.
The cells were incubated at 37°C for 1h in media containing different concentrations of ab120365 (CGP 57380) in DMSO, fixed with 100% methanol for 5 minutes at -20°C and blocked with PBS containing 10% goat serum, 0.3 M glycine, 1% BSA and 0.1% tween for 2h at room temperature. Staining of the treated cells with unpurified ab76256 was performed overnight at 4°C in PBS containing 1% BSA and 0.1% tween. A DyLight 488 goat anti-rabbit polyclonal antibody (ab96899) at 1/250 dilution was used as the secondary antibody. Nuclei were counterstained with DAPI and are shown in blue.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-eIF4E (phospho S209) antibody [EP2151Y] (AB76256)
Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human cervix carcinoma tissue labelling eIF4E with purified ab76256 at 1/50. Heat mediated antigen retrieval was performed using Tris/EDTA buffer pH 9. ab97051, a goat anti-rabbit IgG H&L (HRP) was used as the secondary antibody (1/500). Negative control using PBS instead of primary antibody. Counterstained with hematoxylin.

Immunocytochemistry/ Immunofluorescence - Anti-eIF4E (phospho S209) antibody [EP2151Y] (AB76256)
Immunocytochemistry/Immunofluorescence analysis of untreated, 20% serum treated and 20% serum + LP treated NIH/3T3 cells labelling eIF4E (phospho S209) with ab76256 (left) and eIF4E with ab33766 (right) both at a dilution of 1/500.
Cells were fixed with 100% methanol. ab150077, an Alexa Fluor® 488-conjugated goat anti-rabbit IgG (1/1000) was used as the secondary antibody. DAPI (blue) was used as the nuclear counterstain. ab7291, a mouse anti-tubulin (1/1000) and ab150120, an Alexa Fluor® 594-conjugated goat anti-mouse IgG (1/1000) were also used.
The image shows increased cytoplasmic staining after 20% serum treatment on NIH3T3 cells when compared with no serum treated cells. The LP treatment decreased the increased cytoplasmic staining caused by 20% serum.
ab33766 was used as a Pan control for ab76256. The results showed cytoplasmic staining on no serum, 20% serum and 20% serum +LP treated NIH3T3 cells.

Biological function summary
EIF4E regulates gene expression at the translational level and is a part of the eIF4F complex which also includes eIF4A and eIF4G. This complex is essential for the recruitment of ribosomes to the mRNA impacting the rate of protein synthesis. Changes in eIF4E levels can alter the translational efficiency of specific mRNAs thereby influencing cellular growth and proliferation.
Pathways
EIF4E directly involves in the mTOR signaling pathway which regulates cell growth proliferation and survival. Within this pathway eIF4E interacts with proteins such as 4EBP1 which binds to eIF4E and inhibits its function in the absence of phosphorylation by mTOR. This interaction illustrates the control mechanism of protein synthesis under different cellular conditions connecting it to various signaling cascades.
