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-PIP2;2 antibodies (AS09 490, 1:1000, 1h) and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.
PIP proteins usually show a faint band of dimeric form at 55 kDa addition to the major monomer band of 28 kDa even in the presence of SDS.
- Additional Information
-
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.
Additional information (application): Protein or membrane sample should be treated at 70°C for 10 min before loading on the gel.
Antiboy will weakly react with PIP2;1 and theoretically with PIP2;3, however this protein is very scarcely expressed in plant tissues. The mRNA content is 1 % of that for PIP2;2, therefore reactivity to PIP2;3 was neglegible in our experiments.
Triton X-100 should not be included in the protein extraction buffer, when cell organelles or membrane proteins must be separated from soluble proteins. Because, Triton X breaks membrane structure and solubilizes most membranes proteins. Furthermore, it should be noted that Triton X at high concentrations binds SDS and mask the detergent effect of SDS for SDS-PAGE. Also, micelles of Triton X behave as a large complex with molecular mass of 90 kDa at high concentrations in SDS-PAGE.
