store at -20°C; make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from material adhering to the cap or sides of the tubes.

tested applications

ELISA (ELISA), western blot (WB)

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 and plasma membranes are used, one µg load per well should be sufficient.

Vacuolar membrane protocol is available here.

application example

1.5 µg of crude membrane fraction/lane from Oryza sativa L. cv. Akitakomachi leaf blade and root 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-TIP2;1 antibodies (AS09 509, 1:1000, 1h) and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.

Peptide used to elicti this antibody has been added to primary antibody incubation (right panel, + +) and therefore specific signal has been depleted in this neutralization/immunocompetition assay.
