Description

Immunogen

synthetic peptide corresponding to amino acids 50-65 of human eIF2ε conjugated to KLH. The corresponding sequence is identical in rat and mouse.

Application

Anti-eIF2Bε antibody produced in rabbit is suitable for indirect immunofluorescence (at a dilution of 1:500-1:1,000 using paraformaldehyde fixed NIH-3T3 cells) and western blotting at a dilution of 1:500-1:1,000 using Rat1 or HEK-293T cell lysates.

Biochem/physiol Actions

Translation initiation factor eIF-2B subunit ε is a protein encoded by the EIF2B5 gene in humans. The eIF2B is composed of five subunits α, β, γ, δ and ε, within which the ε subunit is responsible for catalyzing the guanine exchange reaction. Defect in any of these 5 subunits leads to diseases. Mutation in the subunit of eIF2B is associated with an autosomal recessive leukoencephalopathy called Vanishing white matter (VWM).

Target description

eIF2Bε encodes one of five subunits of eukaryotic translation initiation factor 2B (EIF2B), a GTP exchange factor for eukaryotic initiation factor 2 and an essential regulator for protein synthesis.

Physical form

Solution in 0.01 M phos­phate buffered saline, pH 7.4, containing 15 mM sodium azide.
