10 µg of total protein from samples such as beef muscle (1), rat liver (2), Arabidopsis thaliana leaf (3), Hordeum vulgare leaf (4), Synechocystis PCC 6803 total cell (5), Synechococcus PCC 7942 total cell (6) were extracted with Protein Extraction Buffer PEB (AS08 300). Samples were diluted with 1X sample buffer (NuPAGE LDS sample buffer (Invitrogen) supplemented with 50 mM DTT and heat at 70C for 5 min and keep on ice before loading. Protein samples were separated on Bolt 4-12% Tris-Bis gel (Invitrogen) LDS-PAGE and blotted for 1h to 1.5h on PVDF using Bolt Mini Blot Module. Blot was blocked immediately following transfer in 2% blocking reagent (GE RPN 2125; Healthcare) dissolved in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blot was incubated in the primary antibody at a dilution of 1: 5 000 (in blocking reagent) for 1h at room temperature with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, and then washed 1x15 min and 3x5 min with TBS-T at room temperature with agitation. Blot was incubated in secondary antibody (anti-chicken IgY horse radish peroxidase conjugated) diluted to 1:20 000 in blocking reagent for 1h at room temperature with agitation. The blot was washed as above. Signals in the blot were detected using Lumigen ECL Ultra Reagent (Lumigen TMA-6, Lumigen), and visualized using the Molecular Imager VersaDoc MP 4000 System (Bio-Rad) and Quantity One software (Bio-Rad). Exposure time was 30 seconds.
