10 and 20 µg of mitochondrial proteins from cauliflower (Brassica oleracea var. botrytis cv. ’Diadom’) curds (inflorescences) isolated as described by Rurek et al., 2015 (doi: 10.1016/j.bbabio.2015.01.005) were denatured with standard sample buffer (final concentrations in the sample: 2% SDS, 10% glycerol, 50 mM Tris-HCl pH 6.8, 0.1% bromophenol blue, 1% b-mercaptoethanol) at 80oC for 10 min. Proteins were separated on 12% SDS-PAGE and blotted 1h to Immobilon-P (Millipore) using standard Towbin buffer (25 mM Tris, 192 mM glycine, pH 8.3, 20% methanol) supplemented with SDS (0.1%) and semi-dry transfer apparatus (TE77 PWR, Hoefer). Blots were CBB R250 briefly stained (CBB was dissolved in 50% methanol, 7% acetic acid), destained (with this solution without CBB) and wet-scanned (Laser Jet Pro 400 color MFP scanner, Hewlett-Packard). Blots were blocked with 5% skimmed milk (dissolved in PBS-T containing 0.1% Tween 20) in 1h, RT with agitation. Blots were incubated in the primary antibody at a dilution of 1: 1000 for overnight (15 h) at +4ºC with agitation in PBS-T. The antibody solution was decanted and the blot was rinsed briefly, then washed 3 times for 10 min in copious amounts of PBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera; product # AS09 602) diluted to 1:30 000 in 2% milk/ PBS-T for 1h at RT with agitation. The blot was washed as above and developed for 1 min with chemiluminescent detection reagent. Exposure time was: 10, 20, 30 seconds and 1 minute and is indicated on the figure above. MW marker: PageRuler Plus (product #26619) Thermo Scientific (on Western images as dots at the left side on the panels). In red- lot 15D 3650, in blue- lot 16D 2201.
