    Western blot detection using anti-PsaE antibodies

    2 µg of total protein
    from Arabidopsis thaliana leaf (1), Horderum vulgare leaf (2)Chlamydomonas reinhardtii total cell (3), Synechococcus sp.PCC 7942 total cell (4), all extracted with PEB (AS08 300) were separated on  4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following transfer in 2% blocking reagent in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 10 000 for 1h at room temperature 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 room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:20 000 in 2% blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with chemiluminescence detection reagent according the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad).

  • Background
  • Background:

    PsaE is a nucleus encoded subunit of the Photosystem I reaction center. It is located on the stroma side and interacts with PsaF. PsaE may be involved in Fd reduction. Alternative name: Photosystem I 10.8 kDa polypeptide

    This antibody works well with Zea mays. PsaE is detectable in mesophyll cell preparations as well as bundle sheath cells There are minor unspecific bands detectable.
