    western blot detection of PsbC in several species

    5 µg of total protein from (1) Arabidopsis thaliana leaf extracted with Protein Extration Buffer, PEB (AS08 300), (2) Hordeum vulgare leaf extracted with PEB, (3) Chlamydomonas reinhardtii total cell extracted with PEB, (4) Synechococcus sp. 7942 total cell extracted with PEB,  extracted with PEB 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, recommended secondary antibody AS09 602) diluted to 1:25 000 in 2% blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with chemiluminescent 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). Exposure time was 75 seconds.


    western blot using anti-CP43 antibodies

    1.5 µg of chlorophyll from thylakoids of various treatments of Echinochloa crus-galli (1-2), Zea mays (3-5), Pisum sativum (6-7), extracted with 0.4 M sorbitol, 50 mM Hepes NaOH, pH 7.8, 10 mM NaCl, 5 mM MgCl2 and 2 mM EDTA. Samples were denatured with Laemmli buffer at 75°C for 5 min and were separated on 12% SDS-PAGE and blotted 30 min to PVDF using wet transfer. Blot was blocked with 5% fatty acid free milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 3 000 overnight at 4°C with agitation in 1% milk in TBS-T. The antibody solution was decanted and the blot was washed 4 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 1:25 000 in  1 % milk in TBS-T for 1h at RT with agitation. The blot was washed 5 times for 5 min in TBS-T and 2 times for 5 min in TBS, and developed for 1 min with 1.25 mM luminol, 0.198 mM coumaric acid and 0.009% H2O2 in 0.1 M Tris- HCl, pH 8.5. Exposure time in ChemiDoc System was 240 seconds.

    Photosynthetic properties of ?rpoZ. (A) Light-saturated photosynthetic activity of a 1 ml of culture (OD730 = 1) of CS (white bar) and ?rpoZ (black bar) in standard conditions. Each bar represents an average of three independent biological replicates, and the error bars denote SE. (B) Fluorescence at 77 K was measured using 440-nm light that excites Chl. The data were normalized by dividing with the height of the PSI emission peak at 723 nm. (C) Total proteins were isolated, separated with SDS-PAGE and the amounts of PSI reaction center protein PsaB, PSII core protein CP43 and the phycobilisome proteins allophycocyanin (APC) and phycocyanin (PC) were measured by western blotting. The protein contents of PsaB, CP43, ACP and PC were 99 ± 6%, 97 ± 7, 103 ± 7% and 99 ± 4, respectively, in ?rpoZ of that measured in CS.

    Changes of PSII and PSI antenna and core protein levels. Proteins from control and Tl-treated white mustard leaves were separated by SDS-PAGE followed by immunodetection with antibodies against Lhcb1, Lhcb2, Lhca1 (antenna proteins) and D1, D2, CP43, PsbO, PsaA (core proteins). Samples were loaded on the equal amount of chlorophyll (0.25 ?g). Description of samples abbreviation as given in the legend to Fig. 3

  • Additional information: Contains 0,01% ProClin
    Additional information (application): In C4 plants like Echinochloa crus-galli and Zea mays antibody detects 2 bands.
  • Background
  • Background:

    PsbC (CP43) acts as an antenna to the PSII core and its presence seem to be also necessary for maintaining water splitting activity. This protein is more weakly associated with the PSII reaction centre and can be removed from the isolated core.

    Worked very well on thylakoid proteins from Haberlea rhodopensis. We used 3 ug chlorophyll per lane, 1:3000 dilution of CP43, ECL detection of WB. The antibody gave clear single band. It is possible to use lower dilution of CP43.
