Product Name :
eIF4B (phospho-S422) polyclonal antibody Background :
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.It is phosphorylated at Ser-422 by RPS6KA1 and RPS6KB1.phosphorylation enhances the affinity of EIF4B for the EIF3 complex Product :
Rabbit IgG, 1mg/ml in PBS with 0.02% sodium azide, 50% glycerol, pH7.2 Storage&Stability :
Store at 4°C short term. Aliquot and store at -20°C long term. Avoid freeze-thaw cycles. Specificity :
p-eIF4B (S422) polyclonal antibody detects endogenous levels of eIF4B protein only when phosphorylated at Ser422 Immunogen :
Synthetic phosphopeptide derived from human eIF4B around the phosphorylation site of Serine 422. Conjugate :
Unconjugated Modification :

Describe :

Blocking peptides are peptides that bind specifically to the target antibody and block antibody binding. These peptide usually contains the epitope recognized by the antibody. Antibodies bound to the blocking peptide no longer bind to the epitope on the target protein. This mechanism is useful when non-specific binding is an issue, for example, in Western blotting (WB) and Immunohistochemistry (IHC). By comparing the staining from the blocked antibody versus the antibody alone, one can see which staining is specific; Specific binding will be absent from the western blot or IHC performed with the neutralized antibody.
