Applicaton example 
WT-Col-0 Arabidopsis thaliana leaves were frozen in liquid nitrogen and soluble proteins were extracted in a buffer containing 50 mM HEPES, 5 mM NaCl and 10 mM MgCl2. 10 µg, 20 or 40 ug of eparated in SDS-PAGE (15% acrylamide with 6M urea) and blotted 1h to a PVDF membrane using Höefer semi-dry blotter. Blot was blocked with 4 % milk in TTBS for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 overnight in +4°C. The antibody solution was decanted and the blot was washed 3 x 5 min with TTBS 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 1% milk/TTBS for 2h at RT with agitation. The blot was washed 3x5 min in TTBS and 1x5 min in TBS at RT with agitation and developed for 5 min with chemiluminescent detection reagent, according to the manufacturer's instructions.

Open PublicationRedox states of the ??subunit of ATP synthase (CF1?), phosphoribulokinase (PRK) and 2?Cys peroxiredoxins (2?Cys PRX) in dark?adapted plants and plants illuminated under various irradiances.Leaves from 35?day?old Col?0, ntrc and transgenic lines overexpressing (OE) modified TRX systems (OE?NTRC, OE?NTR?TRXf, and OE?SGPS) were collected at the end of the night (D), or from plants illuminated for 2 h at 50 (low light, LL), 200 (growth light, GL) and 800 (high light, HL) ?mol photons m?2 sec?1 and frozen in liquid nitrogen. Total leaf proteins were extracted and separated in sodium dodecyl sulphate–polyacrylamide gel electrophoresis as described in Figure 1 before Western blotting with anti?2?Cys Prx antibody, anti?Cf1? antibody and anti?PRK antibody. Bands corresponding to the oxidized (Ox) and reduced (Red) form of the proteins are marked in the figure. 2?Cys PRX exist as three redox forms, fully oxidized (Ox), partially reduced (1SH) and fully reduced (2SH) (Nikkanen et al., 2016). Ponceau staining was used as the loading control.
