Application examples

Application example

Western blot detection using Arf1 antibody

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 chemiluminescence detection reagent and exposure time for this image was 1 minute.

Protoplasts were extracted in 50mM Tris, 10 mM EDTA and Triton X100, 0.02%.

immunofluorescence using anti-Arf1 antibodies

Immunofluorescence

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.

Background

The ARF1 protein is localized to the Golgi apparatus and has a central role in intra-Golgi transport. It is a small GTPase that undergoes a GDP/GTP nucleotide exchange cycle and it is an important regulator of cellular trafficking.
