Plant/Algal cell antibodies / Membrane transport system / Vacuolar membrane

product information

TIP2-2 belongs to aquaporin protein family and facilitates transport of water and small neutral solutes across tonoplast membrane.

KLH-conjugated peptide derived from C-terminus of Oryza sativa TIP2-2 Q5Z6F0

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.

ELISA (ELISA), western blot (WB)

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.

Protein or membrane sample should be treated at 70°C for 10 min before loading on the gel.

Diluted antibody solution can be used 2 to 3 times within one month if it  contains 0.1 % sodium azide as preservative and is stored at -20ºC to -80ºC.

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;2 C-terminal antibodies (AS09 511, 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.
