Eukarytoic initiation factor 4B (eIF4B) is a general translation factor required for the initiation of global protein synthesis. eIF4B facilitates 5’ cap-dependent translation by directly binding to and stimulating the ATPase and RNA-helicase activity of the eIF4F complex. This interaction is regulated by p70 S6 kinase, which phosphorylates eIF4B to promote formation of the eIF4B-eIF4F complex.Product Details

- Recommended Usage
Each lot of this antibody is quality control tested by Western blotting. For Western blotting, the suggested use of this reagent is 0.5 - 1.0 µg per ml. For immunocytochemistry, a concentration range of 1.0 - 5.0 μg/ml is recommended. For immunoprecipitation, the suggested use of this reagent is 2.5 µg per ml. It is recommended that the reagent be titrated for optimal performance for each application.
- Application Notes
When tested for IP, this clone did not produce strong enrichment of eIF4B. Therefore, this clone may not be suitable for using co-IP to detect low abundant or transient protein-protein interactions.
Due to high sequence conservation between rat eIF4B and the immunogen used to generate this clone, we predict this clone will react with the rat eIF4B ortholog.
During PD testing of this clone for ICC, PFA-fixed HeLa cells were permeabilized with either methanol or Triton X-100. Strong staining was observed using both permeabilization methods.
