|eIF4E in MCF-7 Human Cell Line. eIF4E was detected in immersion fixed MCF-7 human breast cancer cell line using 10 µg/mL Mouse Anti-Human/Mouse/Rat eIF4E Monoclonal Antibody (Catalog # MAB3228) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue).

|Detection of Human/Mouse/Rat eIF4E by Western Blot. Western blot shows lysates of MCF‑7 human breast cancer cell line, Balb/3T3 mouse embryonic fibroblast cell line, and PC‑12 rat adrenal pheochromocytoma cell line. PVDF membrane was probed with 0.1 µg/mL of Mouse Anti-Human/Mouse/Rat eIF4E Monoclonal Antibody (Catalog # MAB3228) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for eIF4E at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.|
eIF4E (eukaryotic initiation factor 4E) interacts with the 7-methyl-GTP cap structure to facilitate the initiation and rate of translation of mRNA. Together with eIF4G and eIF4A, it forms the eIF4F complex. eIF4E activity has been shown to play a role in cell cycle progression, tumorigenesis, embryonic development, nuclear export and synaptic plasticity.
