Application examples application example

western blot detection using CTP6 antibodies

Microsomal (pellet P) and cytosolic (supernatant S) fractions from Arabidopsis thaliana roots were obtained by homogenization in homogenization buffer (50 mM Tris, pH 7.5, 5 mM MgCl2, 10 μM ZnCl2, 2 mM DTT, 100 mM NaCl, 250 mM sacharose) containing protease (Complete Mini, Roche) and phosphatase (PhosSTOP, Roche) inhibitor cocktails and centrifugation at 200,000 ×g for 1.5 h 25 µg of protein were separated on 12 % SDS-PAGE using wet transfer and blotted 1h to ECL nitrocellulose membrane. Blots were blocked with 4% non-fat milk in PBS-T (0.1% Tween-20 in 1× PBS) for 45 min at room temperature (RT) with agitation. Blot was incubated in the primary antibody 50 µg per 1 ml incubation mixture overnight at 4 °C with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, and then washed once for 15 min and 3 times for 5 min in PBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit Gig horse radish peroxidase conjugated, from) diluted to 1:5 000 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 2 minutes. S1 and S2 cytosolic (supernatant) and P1 and P2 microsomal (pellet) fractions were obtained from two independent experiments. Courtesy Dr. Liliana Surmacz, PAN Poland

Background

Background CPT6 (cis-prenyltransferase 6) belong to a group of enzymes which synthesize isoprenoid hydrocarbon skeleton with isoprenoid units in the cis (Z) configuration. AtCPT6 is one of the nine Arabidopsis thaliana CPTs, which catalyze the synthesis of a family of very short-chain polyisoprenoid alcohols of six, seven, and eight isoprenoid units.
