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.
