eEF1B-alpha1 an 2 | elongation factor 1B-alpha 1 and 1B-alpha 2

Recombinant eEF1B-alpha1 protein from Arabidopsis thaliana with no affinity tag,UniProt: Q84WM9, TAIR: At5g12110

24 | 34 kDa

Application example

10 µg total protein extracted from 15 day old Arabidopsis thaliana seedlings that were either kept at 22ºC (1) or heat treated at 38ºC for 2 hours prior to protein extraction (2). As positive control 10 ng of recombinant elongation factor proteins alpha 1 (3) and alpha 2 (4) were separated side by side with the plant samples on 11% SDS-PAGE and blotted to nitrocellulose (Bio-rad). Blots were blocked following transfer with 5% low fat milk in low salt buffer for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 2000 for 2h at room temperature with agitation in the blocking solution. The primary antibody solution was removed and the blot was rinsed briefly twice, then washed 4 times for 15 min each at room temperature with agitation using low salt buffer. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxides conjugated), diluted to 1:2500 for 1h at room temperature with agitation then washed as above and treated with ECL detection reagent according to the manufacturers instructions. Exposure time was 5 seconds. The primary antibody could be reused if it is kept at 4ºC for 2 weeks and if frozen at -20ºC for long time. The pre-immune did not cross react with any plant protein non-specifically. Low salt buffer components are 10 mM Tris (pH 7.6), 68 mM NaCl and 0.05 % Triton X-100.

eEF1B-alpha1 protein belongs to a family of elongation factors, proteins which are involved in translational elongation. This protein is a component of elongation factor B-complex which is composed of 2 elongation B-alpha-(1 and 2), 2 elongation factors B-beta (1 and 2) and 2 elongation factors B-gamma (1 and 2).
