AS18 4166 Anti-ANN-1 | Annexin-1

Recombinant Ann1 (1), Ann4 OE (2). Leaves of Arabidopsis thaliana were ground in liquid nitrogen and total protein was extracted using extraction buffer: Tris pH-8.0 (1M) 5%, EDTA pH-8.0 (0.5 M) 0.2%, β-Mercaptoethanol 0.05%, PMSF (1%) 0.05%, Triton X-100 1%, in distilled water. For each sample, 50 µg of extracted protein was taken, diluted with distilled water and added with 4xLaemli Sample buffer. The samples were denatured at 95℃ for 5 min and were separated on 12 % SDS-PAGE. The samples were blotted for 2 h to PVDF membrane using tank/wet transfer at 4℃ with constant stirring. The blots were blocked with blocking solution (5% dried milk in 1xTBS) for overnight at 4℃ with agitation. Blots were incubated in the primary antibody at a dilution of 1:1000 for 1h at RT with agitation in 5% dried milk in 1xTBS. The antibody solution was decanted and the blots were rinsed briefly, then washed once for 15 min and 3 times for 5 min in 1xTBS at RT with agitation. Blots were incubated in secondary antibody (Goat anti-rabbit IgG (HRP conjugated)) diluted to 1:50 000 in 5% dried milk in 1xTBS for 1h at RT with agitation. The blots were washed as mentioned above and developed for 5 min with chemiluminescent detection reagent in dark room. The exposure time was 10 min.
