    western blot using anti-plant elongation factor antibody eEF1a

    5 µg of total protein from Arabidopsis thaliana (A), Hordeum vulgare (B), Zea mays (C), Physcomitrella patens (P)  extracted with Agrisera PEB buffer  were separated on 4-12 % SDS-PAGE and blotted 70 min to PVDF. Blots were blocked with ECL Advance Blocking Reagent (GE Healthcare)  for 1h at room temperature (RT) with agitation. Blot was incubated for 1 h with either rabbit pre-serum (1: 10 000), rabbit anti-eEF1alpha antibody (1: 10 000) and anti-eEF1 alpha serum incubated with eEF1alpha synthetic peptide (in 100 mM excess to saturate a signal from specific antibody) for 1h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602, Agrisera ) diluted to 1:50 000 in  for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturers instructions. Exposure time was  2 minutes.

    Western blot using anti- plant eEF1a antibodies

    Solanum tuberosum - 20 µg total protein extracted with Agrisera 4xPEB buffer (1), Solanum tuberosum - 20 µg total protein extracted with 50mM Tris and precipitated after with 10%TCA/acetone, the protein pellet was solubilized in urea/thiourea/CHAPS​ (2), Arabidopsis thaliana total protein 20 µg (3). The total soluble protein was extracted by adding 10%TVA/acetone to the grinded plant material and after washing with acetone 80-100 % the protein pellet was solubilized in SDS buffer. Samples were denaturated 5 min/70°C. PAGE and WB:​ The samples were separated on 10 % SDS-PAGE and blotted for 75 min on nitrocellulose membrane using wet transfer. The blot was blocked with 5 % milk in TBS-0.1%Tween20 overnight at 4°C. The blot was incubated with primary antibody rabbit eEF-1a at a dilution 1:1000 (before optimization) or 1: 10 000 (after optimization) in TBS-T for 1h/RT with agitation. The Ab solution was decanted and the blot was rinsed briefly twice, 1x 15 min, and 3x 5min in TBS-T at RT with agitation. Blot was incubated with the matching secondary Agrisera anti-rabbit HRP antibody (AS09 602), at a dilution 1:20 000 for 1h with agitation at RT. The blot was washed as above and developed with Agrisera ECL SuperBright. The exposure time was 10 and 15 sec.​

  • Additional Information
  • Additional information (application):

    This product can be sold containing ProClin if requested.

    Following protein resolubilization with urea/thiourea/CHAPS signal strength of recognized band is decreased. Recommended protein extraction conditions are without urea.

  • Background
  • Background:

    EF1A (elongation factor 1-alpha) belongs to the GTP-binding elongation factor family and is localized in the cytoplasm. It is an essential enzyme in elongation phase of protein synthesis. There are four genes encoding EF1A in Arabidopsis, sequences of genes 1,2 and 3 are identical. Synonymes:eEF-1A.
