  • Application Examples
  • Application example

    western blot using anti-RpoB antibodies for Arabidopsis
    Stroma, thylakoid and total protein from Arabidopsis thaliana were extracted with 50 mM HEPES-KOH pH 8, 330 mM sorbitol exaction buffer. Components were separated on 12% SDS-PAGE and blotted overnight to Nitrocellulose membrane using wet transfer. Blots were blocked with 5% non-fat milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 500 for 2h 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) diluted to 1:10 000 in for 1h at RT with agitation. The blot was washed as above and developed for 5min with chemiluminescent reagent of extreme low femtogram range. Exposure time was 120 seconds.

  • Additional Information
  • Additional information (application): Antibody does not work on total cell extracts. Stromal fraction has to be used.
    This antibody is detecting recombinant RpoB.
  • Background
  • Background: RpoB (RNA polymerase beta subunit (chloroplast)) is a DNA-dependent RNA polymerase which catalyzes the transcription of DNA into RNA using the four ribonuceloside triphosphates as substrates.
