Application example
Thylakoid membranes from Arabidopsis (0.05-0.75 µg of Chl) were separated on 14%AA+ 6M urea gels and blotted 1h to PVDF. Blots were blocked immediately following transfer in 5% milk solution for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 20 000 o.n. at 4°C with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 15 min and 3 times for 5 min in TBS-T at room temperature with agitation. Blots were incubated in secondary antibody, HRP conjugated, diluted to 1:5 000. The blots were washed as above and developed for 5 min with ECL-Plus detection reagent according to the manufacturers instructions. Exposure time was 1 min in CCD camera Fuji4000.

Open PublicationMembrane protein complexes of PSII and PSI survive in the 35S:A9 seedlings.(A) Western detection of complexes after the H2O2 treatments. The PSII complexes (top) separated by BN-PAGE were detected using anti-D1 (DE-loop) antibodies at 1/5,000 dilution. The PSI complexes (bottom) were detected using anti-PsaB antibodies at 1/4,000 dilution. PSII symbols: •, and the bracket on top respectively mark the dimeric PSII complex, and the PSII-LHCII super-complexes. The asterisk marks the CVII (CP43-less PSII monomer) complex. PSI symbols: • marks the PSI-LHCI super-complex that co-migrates in our gel system with the dimeric PSII complex; the asterisk marks the PSI monomer. (B) The PSII complexes also withstand drastic dehydration. The thylakoid samples were analyzed immediately (0 h) after the dehydration treatment (DT), and following rehydration for 16 h, DT (16 h). In this case the complexes were detected using anti-D1 (C-terminal) antibodies at 1/15,000 dilution. An additional PSII complex mentioned in the text is indicated: CV (**, PSII monomer).

Open PublicationCGL160 is a membrane-integral chloroplast protein located in non-appressed thylakoid membranes.A. Subcellular localization of CGL160. Immunoblot analysis performed on initial plant extract, isolated chloroplasts or isolated mitochondria. TOM40 is a marker for the mitochondrion. B. Suborganellar localization determined by immunoblot analysis of chloroplast proteins diagnostic for photosystem I (PsaA), photosystem II (D1), Rubisco, LHCII (LHCB1.2) and CGL160. Protein extracts were separated by SDS-PAGE and probed with specific antibodies directed against PsaA, (PSI reaction center subunit), D1 (PSII reaction center subunits), LHCB1 (outer PSII antenna protein), the large subunit of Rubisco, a soluble protein in the stroma, and CGL160. C. Immunoblot analysis show that CG160 is an integral membrane protein associated with the thylakoid membranes. Isolated thylakoid membranes were washed with 0.4 M NaCl, and the thylakoid membranes and the supernatant were probed by immunoblotting with antibodies against CGL160 and the PSII reaction center protein D1.

Additional information: Antibody will detect 23 kDa N-terminal fragment Additional information (application): Antibody is recognizing a 23 kDa fragment in spinach and Arabidopsis thylakoidsfor usage on total cell extracts the dilution needs to be determined experimentally - Background
-
Background: The psbA gene has been cloned from many species of plants, green algae, and cyanobacteria. The psbA gene is located in the chloroplast genome and encodes for the D1 protein, a core component of Photosystem II. PsbA/D1 is rapidly cycled under illumination in all oxygenic photobionts. Tracking PsbA pools using the Global PsbA antibody can show the functional content of Photosystem II in a wide range of samples. Alternative names: 32 kDa thylakoid membrane protein, photosystem II protein D1

Martina Giovanardi | 2016-10-19We used this antibody on the green microalga Neochloris oleoabundans and it worked really well. Loading 0.5 µg of Chlorophyll we got very strong signal without aspecific bands.Jun Liu | 2014-01-14This antibody has been working well. It always gave a strong signal around 30 kDa in Arabidopsis, wheat and rice.
