    western blot using anti-RDR2 antibodies

    50 µg of total protein from Arabidopsis thaliana: rdr2-1 mutant, T-DNA insertion first exon (a), 30 µg protein from wild-type Col-0 (b), 50 µg protein from wild-type Col-0 (c),  extracted with extraction buffer (50 mM Tris pH 7.5; 150 mM NaCl; 1 mM EDTA; 10 % v/v Glycerin; 1 mM DTT, 1x Complete Protease Inhibitor Cocktail, Roche) and denatured with Laemmli buffer at 95°C/5 min., were separated on 7.5 % SDS-PAGE and blotted 1.5 h to PVDF using tank transfer. Blots were blocked with blocking buffer (5% milk powder; 1x TBS; 0.1% Tween-20) overnight at 4°C with agitation. Blot was incubated in the primary antibody at a dilution of 1:10000 (a,b) and 1: 5000 (c) for 2h at RT with agitation. The antibody solution was decanted and the blot was rinsed briefly and then washed tree times for 15 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602) diluted to 1:20 000 in blocking buffer for 1h at RT with agitation. The blot was washed as above and developed for 5 min with chemiluminescent detection reagent and exposed to Amersham Hyperfilms ECL for 20 seconds.
