25 µg of total protein from the indicated Arabidopsis thaliana wilde type and gpa1-3 mutant were extracted with extraction buffer ( 250 mM sucrose, 100 mM HEPES-KOH pH 7.5, 5% glycerol, 1mM Na2MoO4 x 2H2O, 25mM NaF, 10 mM EDTA, 1mM DTT, 0.5% Triton X-100, protease inhibitor cocktail) and denatured with SDS loading dye (50 mM Tris-HCl pH6.8, 100mM DTT, 2%SDS, 10% glycerol, 0.025% bromophenol blue) at 70°C for 2-5 min were separated on 10% SDS-PAGE and blotted 1h to PVDF using tank transfer. Blots were blocked with Tris-buffered saline containing 0.05% Tween-20 (TBS-T) and 5% skimmed milk powder for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody (anti-GPA1, AS12 2370) at a dilution of 1: 5 000 overnight at 4°C with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed 5 times for 15 min in TBS-T with milk powder at RT with agitation. Blot was incubated in secondary antibody (Goat-Anti-Rabbit HRP conjugate, AS09 602) diluted 1:5000 for 2h at RT with agitation. The blot was washed as above with TBS-T without milk powder and then developed with Thermo Scientific SuperSignal West Substrate (pico and femto mixed 1:1), before exposure to a CEA RP NEW film for 10min.
