RBOHD | Respiratory burst oxidase homolog protein D

Application example

Total proteins were isolated from 10 or 12 seedlings of 7-day-old Arabidopsis thaliana seedlings of Col-0 (wild-type) and rbohd null mutant (Nühse et al., 2007). 16 µl of total proteins were denatured at 65°C for 5 min, separated on an 8 % SDS-PAGE. and transferred for 70 min at 55V using a tank transfer system to nitrocellulose membrane. Blots were blocked with 1xPBS+0.1% Tween 20 + 5 % milk (PBS-T) or TBS + 0.1 % Tween 20 (TBS-T) + 5 % milk for 2 h at room temperature (RT) with agitation. Primary antibodies were diluted as indicated to 1: 2,500 and 1: 5,000 respectively and incubated ON at 4ºC with agitation in 1xPBS-T pr TBS-T + 5 % milk. The primary antibody solutions were decanted, and the blots were washed 3 times (7 min. each) in 1xPBS-T or TBS-T at RT with agitation. Blot was incubated with secondary antibody goat anti-rabbit HRP conjugated (AS09 602, Agrisera) diluted to 1: 20, 000 and developed with chemiluminescent detection reagent, accodring to manufacture's recommendations. Exposure time was 2 min. for X-ray film. As a control part of the same membrane was incubated with anti-CNX1/2 antibodies (AS12 2365, Agrisera).
