Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified E B
Eukaryotic Initiation Factor 2B (eIF2B) plays a key role in the initiation of mRNA translation in eukaryotic cells by acting as a guanine nucleotide exchange factor. The activity of eIF2B is regulated by a wide array of conditions. Stress inhibits its action, while stimulation of protein synthesis results in its activation. eIF2B , an 82kD subunit of eIF2B, is phosphorylated at serine 539 by glycogen synthase kinase-3 (GSK-3), which leads to inhibition of its guanine nucleotide exchange activity.
Catalog #E8949-21B
ApplicationsSuitable for use in Western Blot. Other applications not tested.
Recommended DilutionsWestern Blot: 1:1000.
