EIF4B pSer422 Rabbit Polyclonal Antibody

Specifications

Product Data
Applications	IHC, WB
Recommend Dilution	Western Blot: 1/500-1/1000. Incubate membrane with diluted antibody in 5% nonfat milk, 1xTBS, 0.1% Tween-20 at 4°C with gentle shaking, overnight. Immunohistochemistry on Paraffin Sections: 1/50-1/100.
Reactivity	Human, Mouse
Host	Rabbit
Clonality	Polyclonal
Immunogen	Synthetic phosphopeptide derived from Human eIF4B around the phosphorylation site of Serine 422 (T-G-Sp-E-S).
Specificity	This antibody detects endogenous levels of eIF4B only when phosphorylated at Serine 422.
Formulation	PBS (without Mg2+ and Ca2+), pH 7.4, 150 mM NaCl, 0.02% Sodium Azide and 50% Glycerol. State: Aff - Purified State: Liquid purified Ig fraction.
Concentration	lot specific
Purification	Immunoaffinity Chromatography using epitope-specific phosphopeptide. The antibody against non-phosphopeptide was removed by chromatography using non-phosphopeptide corresponding to the phosphorylation site.
Conjugation	Unconjugated
Storage Condition	Store the antibody (in aliquots) at -20°C. Avoid repeated freezing and thawing.
Gene Name	eukaryotic translation initiation factor 4B
Database Link	Entrez Gene 75705 MouseEntrez Gene 1975 Human UniProt ID P23588
Background	eIF4B is required for the binding of mRNA to ribosomes. It functions in close association with eIF4F and eIF4A. It binds near the 5'-terminal cap of mRNA in the presence of eIF4F and ATP. It promotes the ATPase activity and the ATP-dependent RNA unwinding activity of both eIF4A and eIF4F (referenced from swissprot).
Synonyms	Eukaryotic translation initiation factor 4B, eIF-4B
Note	Molecular Weight: 80 kDa
Reference Data
Protein Pathways	mTOR signaling pathway
