C., Yanagisawa, M., et al. Impact Factor: 5.139 Open Publication Silver staining and Western blot analyses of protein extracts from the isolated dimorphic chloroplasts. Two micrograms of proteins from total chloroplasts (lane 1), peripheral chloroplasts (lane 2) and central chloroplasts (lane 3) were separated on SDS/12% PAGE. Molecular weights are shown on the left in kilodaltons. (A) Total proteins were visualized by silver staining. Polypeptides of the highly abundant pyruvate orthophosphate dikinase (PPDK), Rubisco large-subunit (LSU) and small-subunit (SSU) are indicated. Other bands of significantly different intensities between the dimorphic chloroplasts are indicated by arrowheads. (B) Resolved proteins were electroblotted onto nitrocellulose membranes and probed with antibodies against PPDK, LSU, Photosystem II manganese-stabilizing protein (PsbO), cytochrome f (Cyt-f), or Photosystem I subunit II (PsaD). (C) The immunoblots were analyzed by densitometric quantification. The abundance of each protein in peripheral (P-Chls) and central (C-Chls) chloroplasts was calculated relative to that of total chloroplasts and shown with standard errors, after three (PsbO) or four (others) independent experiments. Reactant: Mus musculus (House mouse) Application: Western Blotting Pudmed ID: 31245706 Journal: Plant Direct Figure Number: 5A Published Date: 2018-02-01 First Author: Rantala, S. & Tikkanen, M. Impact Factor: None Open Publication Stepwise detachment of photosynthetic protein complexes from the thylakoid membrane of WT, stn7, stn8, stn7stn8, and tap38/pph1. Thylakoid membranes of WT, stn7, stn8, stn7stn8, and tap38/pph1 plants harvested from moderate growth light (GL, 120 ?mol photons m?2 s?1) or after high light illumination (HL, 600 ?mol photons m?2 s?1 for 2 hr) were isolated and solubilized with 0%, 0.25%, 0.5%, 1%, and 2% DIG. Equal volumes of the soluble supernatant (S) and insoluble pellet (P) fractions were loaded and separated in SDS?PAGE followed by immunodetection of (a) proteins D1, PSAB, CYTF, and ATPF representing the protein complexes PSII, PSI, LHCII, Cyt b6f, and ATP synthase, respectively, as well as (b) proteins LHCB1, P?LHCB1, LHCB2, P?LHCB2, and LHCB3, representing the different subunits of the LHCII complexes. The differences in mutants with respect to WT as well as the differences in WT in response to Hl are marked with white boxes. Representative data from three different biological replicates are shown Reactant: Solanum lycopersicum (Tomato) Application: Western Blotting Pudmed ID: 34439953 Journal: Biology (Basel) Figure Number: 9A Published Date: 2021-07-28 First Author: Trojak, M. & Skowron, E. Impact Factor: None Open Publication Western Blot analyses (a) and densitometric analyses of PsbS (b), VDE (c), PGRL1 (d), and cytf (e) proteins in leaves of tomato plants (Solanum lycopersicum L. cv. Malinowy Ozarowski) grown under different light conditions (see Material and Methods for details). The bands were normalized to the appropriate ? subunit of ATP synthase (ATPB) band (loading control, Figure S4) (a). The bar diagrams (b–e) represent pixel volumes (densitometric analyses) of proteins in samples. Each value represents the mean ± SD (n = 3) considering the control sample (WL) value as 1 (100%). Different letters indicate significant differences between treatments (p = 0.05) with a Tukey’s HSD test. MW—molecular weight.
Picture (footer):	Application example 1.0 µg of chlorophyll from pea (C3 plant) and from mesophyll (M) and bundle sheath (BS) thylakoids of various treatments of Zea mays, Echinochloa crus-galli, Panicum miliaceum (C4 plants) extracted with 0.4 M sorbitol, 50 mM Hepes NaOH, pH 7.8, 10 mM NaCl, 5 mM MgCl2 and 2 mM EDTA. Samples were denatured with Laemmli buffer at 75 0C for 5 min and were separated on 12% SDS-PAGE and blotted 30 min to PVDF using wet transfer. Blot was blocked with 5% milk in TBS for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 3000 overnight at 40C with agitation in 1% milk in TBS-T. The antibody solution was decanted and the blot was washed 4 times for 5 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602, Lot 1711) diluted to 1:25 000 in 1 % milk in TBS-T for 1h at RT with agitation. The blot was washed 5 times for 5 min in TBS-T and 2 times for 5 min in TBS, and developed for 1 min with 1.25 mM luminol, 0.198 mM coumaric acid and 0.009% H2O2 in 0.1 M Tris- HCl, pH 8.5. Exposure time in ChemiDoc System was 125 seconds.

Blot was blocked with 4% milk for 2 h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1:3000 (PC and PetA, simultaneous western blot detection for both antibodies at the same time) for 1 h/RT with agitation in PBS-T. The antibody solution was decanted and the blot was rinsed briefly, then washed 3 times for 5 min in PBS-T at RT with agitation. Blot was incubated in Agrisera matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:25000 in for 1 h/RT with agitation. The blot was washed as above and developed for 5 min with chemiluminescent detection reagent according to manufactures recommendations. Exposure time was 30 seconds. Simultaneous western blot detection can be applied if MW of detected proteins differs in min. 20 kDa. Courtesy Dr. Anja Liszkay, CNRS, France

additional information (application):	This antibody can be used to identify di and monomeric cytb6-f complexes Kaňa et al. 2020.
background:	Multi-subunit complex of cytb6/f is a crucial component for the photosynthetic electron transport chain of higher plants, green algae and cyanobacteria. This complex is catalyzing oxidation of quinols and the reduction the reduction of plastocyanin. This reaction allows to establish the proton force required for the ATP synthesis. Four major subunits build the complex: the petA gene product corresponding to a c-type cytochrome (cytf), the petB gene product corresponding to a b-type/c’-type cytochrome with three haems (cyt b6), the petD gene product (subunit IV, or suIV), and the petC gene product, corresponding to the Rieske/Iron/sulfur protein.
