Application examples Application example

Western blot using anti-PGR5 antibodies

Thylakoids were isolated according to Sirpiö et al (2011, Methods Mol Biol. 2011; 775:19-30). 3 µg/µl of total chlorophyll from Arabidopsis thaliana col-0 (1) and Arabidopsis thaliana pgr5 mutant (Munekage et al. 2002, Cell) (2) were denatured in Laemmli buffer at room temperature (15 min) were separated on 12 % SDS-PAGE mini-gels with 6 M urea and blotted for 1h to a PVDF membrane using a semi-dry transfer. Membranes were blocked with 5% milk in TBS for 1h at room temperature and incubated in antisera (1:1000 in 1 % milk/TTBS) overnight at 4°C with slow agitation, then in secondary antibody (anti-rabbit IgG HRP conjugated, AS09 602, Agrisera) 1:20 000 in 1% milk/TTBS) for 2 hours at RT with slow agitation. Blots were detected for 5 min with a chemiluminescent substrate. Exposure time was 2 min.

The pgr5 mutant has a point mutation that affects the function of the PGR5 protein, therefore a band is still seen in the western blot.

Background

Background PGR5 (Protn gradient regulation 5) is involved in the regulation of the cyclic electron flow (CEF) around Photosystem I and cellular response to light intensity and photoprotection. Essential for the reduction of PGRL1A by ferredoxin and for photoprotection.
