Application examples

Application example

20 - 1.25 µg of soluble proteins from senescing or young leaves of oilseed rape (Brassica napus L.) extracted with citrate sodium-phosphate buffer (100 mM, pH 6.8) and were separated on 12% SDS-PAGE and blotted 10 min to PVDF using semi-dry transfer (see Desclos et al. 2009). Blots were washed with TBS-T 3 times for 15 min at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2 000 (prepared in TBS-T with 5% low fat milk) for 2h or 1h30min at RT with agitation. The antibody solution was decanted and the blot was washed 5 times for 5 min in TBS-T and 3 times for 5 min in TBS at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:0 000 in for 1h at RT with agitation. The blot was washed as above and developed for 5 min with ECL according to the manufacturer's instructions. Exposure time was 1 second.

Background

Background Senescence-specific cysteine protease (SAG12) is a cysteine protease influenced by cytokinin, auxin and sugars and involved in developmental senescence specific cell death.
