Application examples

Application examples Application example

western blot using anti-HTA9 antibodies

1) hta9, hta11 double mutant, about 1 ug protein; 2) mutant hta9, hta11 about 2 ug protein; 3) wild-type about 2-3 ug protein; 4) wild-type about 4-5 ug protein from Arabidopsis thaliana
Protein from Arabidopsis histone preparation (acid extracted, precipitated with acetone and resuspended in urea). Denatured with SDS-PAGE buffer at 90C for 2 min, separated on 15% SDS-PAGE and blotted 1h to PVDF tank transfer. Blots were blocked with PBS + 3% BSA overnight at 4C with agitation. Blot was incubated in the primary antibody at a dilution of 1:1 000 in PBS + 3% BSA for 1h at RT with agitation. The antibody solution was decanted and the blot was rinsed once with PBS-T for 5 min. Blot was incubated in secondary antibody PBS + 3% BSA (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602) diluted to 1:25 000 for 1h at RT with agitation. The blot was washed 3-4 times with PBS-T for 5 min. The blot was developed with Immobilion (Millipore) and exposed on an X-ray film for 1 min.
