Product Overview
Clone 18E95 is a rabbit monoclonal antibody that recognizes eukaryotic initiation factor 4A-I (gene EIF4A1) in human, mouse and rat samples and is validated for Western blot, ICC/IF and flow cytometry. The predicted molecular weight is 46.2 kDa, and the supplier reports an observed band at about 46 kDa.
eIF4A1 is a DEAD-box RNA helicase and part of the cap-binding eIF4F complex. It unwinds secondary structure in mRNA 5′ untranslated regions so the small ribosomal subunit can bind and scan, and it is studied in translation control and as a target of natural product inhibitors such as silvestrol.

Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:500 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human eIF4A1.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places eukaryotic initiation factor 4A-I in the cytoplasm and cell membrane. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
