application example

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 standard ECL and exposure time for this image was 1 minute.

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