application example

western blot using anti-STM antibodies


10 µg of total protein from Arabidopsis thaliana seedling tissue extracted with Exractions buffers 1 or 2 (see below) were separated on 10 % SDS-PAGE and blotted 1h to PVDF using semi-dry transfer. Blots were blocked with milk for 2h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1000 in milk overnight at 4°C with agitation. The antibody solution was decanted and the blot was rinsed twice with milk, then washed once for 5 mins with PBS, 10 mins with 2% milk + PBST, 5 mins with PBST at RT with agitation. Blot was incubated in secondary antibody (goat anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera AS09 602) diluted to 1:75 000 in for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was variable.
