Application examples

Application example

Western blot using anti-Sec21p

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. Signal was detected with chemiluminescent detection reagent, exposure time was 1 minute.

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

Immunofluorescence

immunofluorescence using anti-Sec21 antibodies

Immunofluorescence labelling of rabbit anti-SEC21 (gamma subunit of COP vesicles; red) in 5-day-old root epidermal cells of Arabidopsis thaliana expressing ER-mGFP5-HDEL (ER marker; green). The 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).
