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

KLH-conjugated peptide derived from Arabidopsis thaliana SAG12 protein sequence, UniProt:Q38886, TAIR: AT5G45890

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum in PBS, pH 7.4
Format Lyophilized in PBS pH 7.4.
Quantity 50 ĩg
Reconstitution For reconstitution add 50 ĩl of sterile water.
Storage Store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.
Tested applications Western blot (WB)

application example

western blot using anti-SAG12 antibodies

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, from Bio-Rad) 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.
