Application examples

Application example

25 µg (1) or 50 µg (2) of mitochondria, isolated from 14-day old Col-0 plants (Arabidopsis thaliana) grown in hydroponic cultures, were separated on a 12.5% acrylamide-SDS-PAGE. The unstained peqGOLD low molecular weight (LMW) protein marker was used as a molecular weight standard. The gel was subsequently incubated in transfer buffer (40 mM glycine, 100 mM Tris, 0.375 % (w/v) SDS, pH 8.9-9) for 30 minutes at room temperature. Semidry western blotting was performed with 3 layers of whatman paper soaked in transfer buffer and blotted at 0.8 mA/ cm2 gel for one hour at room temperature. Blocking was performed for one hour in TBS-T (150 mM NaCl, 10 mM Tris pH 7.4, 0.1 % (v/v) Tween-20) with the addition of 3 % (w/v) non-fat milk at room temperature. Primary antibody (1:2000 dilution) incubation was performed at 4°C/ON in the presence of 1 % (w/v) non-fat milk in TBS-T. Secondary antibody goat anti-rabbit HRP conjugated (AS09 602 Agrisera), at 1:10 000 dilution) was incubated 1h/RT in TBS-T. Chemiluminescence was detected using a 1:1 ratio mixture of ECL 1 (100 mM Tris, 1 % (w/v) luminol, 0.44 % (w/v) coumaric acid, pH 8.5) and ECL 2 (100 mM Tris, 0.18 % (v/v) H₂O₂, pH 8.5) solution and visualized using an Image QuantLAS4000 image visualizer (GE healthcare). The membrane was exposed for 60 seconds.
UCP was detected at a size of approximately 29 kDa.

10 μg of mitochondrial fraction from Arabidopsis thaliana and 25 μg of Arabidopsis thaliana leaf extract were separated on 10% gel and blotted on nitrocellulose membrane using wet transfer (0.22% CAPS, pH 11). Filters where blocked (1.5h) in 5% milk in TBST (1X TBS, 0,1% Tween 20), incubated with 1: 5000 anti-UCP antibodies (2h in TBST) followed by incubation with 1: 10 000 secondary anti-rabbit (1h) HRP-coupled antibodies from Agrisera, AS09 602 and visualized with standard ECL on Kodak autoradiography film for 15-60 s. Mitochondria were isolated as described by Urantowka et al. (Plant Mol Biol, 2005, 59:239-52). Mitochondrial pellets were suspended in 1X Laemmli buffer (5% beta-mercaptoetanol, 3.7% glycerol, 1.1% SDS, 23 mM Tris- HCl pH 6.8, 0.01% bromophenol blue), heated (95°C, 5 min.) and centrifuged (13 000rpm, 1 min.). Leaf extracts were prepared as described by Martinez-Garcia et al. (Plant J., 1999, 20:251-7).

Additional information

Peptide used to elicit this antibody is conserved in both isoforms, UCP1 and UCP2 of Arabidopsis thaliana.

Background

UCP (uncoupling protein) is an inner membrane mitochondrial protein that can dissipate the proton gradien before it can be used to provide the energy for oxidative phosphorylation. Synonymes: AtUCP, Uncoupling protein 2.
