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.

Method for plant ER isolation is available here.

application example



crude membrane fraction/lane from Arabidopsis thaliana stems (1,3) and crude membrane fraction from yeast cells expressing SIP2;1 (2,4) 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-AtSIP2;1 antibodies (AS09 496, 1:1000, 1h) and secondary anti-rabbit (1:2000, 1 h). All steps were performed in RT with agitation.

Peptide used to elicit anti-SIP2;1 antibodies have been incubated with antibodies - right panel.
