Additional information

0.1 % sodium azide is added as preservative. For antibody re-suspending information check the tube lable.

Antibodies will detect target protein in a few µg of a crude preparation loaded per well. If purified preparations of vacuolar membranes are used, one µg load per well should be sufficient.

Protocol of isolation of plant vacuolar membranes can be found here.

application example



1 µg and 10 µg of crude membrane fraction/lane from Arabidopsis thaliana were separated on 12 % SDS-PAGE and blotted 1h to PVDF membrane (40 min. at 10 V using BioRad semidry transfer). Filters were blocked 1h with 5 % low-fat milk powder in TBS-T (0.05% Triton X.100). Membranes were washed 5 times with TBS-T, each time in a fresh polystyrene box and probed with anti-AJ011604 | nitrate transporter antibodies (AS09 466, 1:2000, 1h) and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.
