Application examples

Application examples Application example

western blot using anti-GAI antibodies
20 µg of total protein from Arabidopsis thaliana Columbia-0 plants grown on agar plates (MS 1 % sucrose) in LD conditions (16 h light, 8 h dark). Protein extraction was done using TRIZOL protocol on samples taken every 4 hours from the time point lights were switched on (Zeitgeber Time 0). Marker was 10 µl of BLUEstain™ Protein ladder, 11-254 kDa (GoldBio). Samples were separated on 12 % SDS-PAGE run at 200 V on Mini-Protean and blotted 1h to nitrocellulose. Blots were blocked with TBST (TBS+0.1 % Tween, 5 % non-fat, dry milk) for over night at 4°C with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for 2h at RT with agitation in TBS-T. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera AS09 602) diluted to 1:00 000 in for 1h at RT with agitation. The blot was washed as above and developed with BIO-RAF Chemi-doc. Exposure time was 5 minutes.

Homogenization with thiourea and bead beater.

Protocol for protein extraction from seeds can be requested here.

GAI protein is present in very low levels therefore specific material should be used for analysis as well as chemiluminescence detection reagent in extreme low femtogram range, as AgriseraECLSuperBright
