application example

western blot using anti-PSB33 antibodies

Specified µg/ul of chlorophyll from Arabidopsis thaliana leaf extracted with sample buffer (2% SDS, 8% sucrose, 0.2mM EDTA, 10mM Tris HCl (pH 6.8) 4% beta-mercaptoethanol) were separated on 15 % SDS-PAGE and blotted 1h to PVDF. Blots were blocked with 10 % milk for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 4 000 overnight at 4°C with agitation. 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) diluted to 1:20 000 in for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL West Pico (34080, Thermo) according to the manufacturer's instructions. Exposure time was 60 seconds.
