50 µg of total protein from (1) Nicotiana tabacum protoplast total protein, (2) Arabidopsis thaliana protoplast soluble protein, (3) Arabidopsis thaliana protoplast total protein were separated on 10 % SDS-PAGE and blotted 2h to nitrocellulose (Semi-dry, 200mA). Filters were blocked over night with 5% low-fat milk powder in TBS and probed with anti-Sec21p antibodies (AS08 327, 1:1000, 1h) and secondary anti-rabbit (1:20000, 1 h) antibody (HRP) in TBS-Tween (recommended secondary antibody AS09 602). Signal was detected with standard ECL andexposure time for this image was 1 minute.
Protoplasts were extracted in 50mM Tris, 10 mM EDTA and Triton X100, 0.02%.
Specificity testing of rabbit anti-ARF1 serum. Immunofluorescence labelling of rabbit anti-ARF1 antibody (red) in 5-day-old root epidermal cells of the Arabidopsis thaliana ecotype Columbia-0 (WT) or seedlings expressing the ADP-RIBOSYLATION FACTOR 1 (AtARFA1c; accession At2g47170) fused to EGFP (green) (Xu, J. and Scheres, B. 2005. Plant Cell 17, 525-536). The rabbit anti-ARF1 antibody was diluted 1:1000 and the secondary antibody, donkey anti-rabbit CY5-coupled (Jackson ImmunoResearch) was diluted 1:300. The nuclei were stained with DAPI (blue). Note the co-labelling of ARF1-GFP with the anti-ARF1 antibody (arrowheads) and the additional labelling (potentially of other ARF1 variants) by the anti-ARF1 antibody (arrows). The antibody staining permeability was limited to the 1-2 outermost layers of the whole-mounted root tips.
