  • Application Examples
  • Western blot using anti-oleosin 21.2 kDa antibodies

    Homogenates of dry seeds of Arabidopsis thaliana wild-type (left panel), oleosin-deficient mutants: ole4, ole3, ole1 and ole2 (from left to right following wild-type) were freshly extracted with 2x SDS-sample buffer (+ 2ME) for SDS-PAGE and denatured with 4X SDS buffer at 95°C for 5 min. were separated on 15 % SDS-PAGE and blotted to PVDF membrane. Blot was blocked with 5 % skim milk/TBS-T, 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2000 in TBS-T for 1h/RT. The antibody solution was decanted and the blot was washed 4 times for 10 min in TBS-T at RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in for 1h/RT with agitation. The blot was washed as above and developed with a chemiluminescent detection reagent, following manufacture's recommendations.
  • Background
  • Background: Oleosins may have a structural role to stabilize the lipid body during desiccation of the seed by preventing coalescence of the oil. Probably interacts with both lipid and phospholipid moieties of lipid bodies. May also provide recognition signals for specific lipase anchorage in lipolysis during seedling growth. Oleosins also increase the viability of over-wintering oilseeds by preventing abnormal fusion of oil bodies during imbibition in the spring. Cellular localisation: surface of oil bodies.
