Related Product Information for anti-eIF4B antibody
Description: Required for the binding of mRNA to ribosomes. Functions in close association with EIF4-F and EIF4-A. Binds near the 5'-terminal cap of mRNA in presence of EIF-4F and ATP. Promotes the ATPase activity and the ATP-dependent RNA unwinding activity of both EIF4-A and EIF4-F.

Post Translational Modifications: Phosphorylated at Ser-422 by RPS6KA1 and RPS6KB1; phosphorylation enhances the affinity of EIF4B for the EIF3 complex.

Subunit Structure: Self-associates and interacts with EIF3 p170 subunit.

Product Notes

The eIF4B eif4b (Catalog #AAA9610630) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Phospho-eIF4B (Ser497) Antibody reacts with Human, Mouse, Rat Predicted: Bovine, Horse, Sheep, Rabbit, Dog and may cross-react with other species as described in the data sheet. AAA Biotech's eIF4B can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunohistochemistry (IHC), Peptide ELISA (EIA). WB: 1:500-1:2000 IHC: 1:50-1:200 ELISA (Peptide): 1:20000-1:40000. Researchers should empirically determine the suitability of the eIF4B eif4b for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "eIF4B, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.
