Application examples

western blot using anti-PsbS antibodies

5 µg of total extract from (1) Arabidopsis thaliana leaf,  (2) Spinacia oleracea  (3) Hordeum vulgare (4) Zea mays extracted with PEB (AS08 300) were separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following transfer in 2% ECL Advance blocking reagent (GE Healthcare) in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 10 000 for 1h at room temperature 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 (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:50 000 in 2% ECL Advance blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with ECL Advance detection reagent according to the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad). Exposure time was 30 seconds. 


western blot using anti-PsbS rabbit antibodies
50 mg of leaf tissue from 3-4 week old Arabidopsis thaliana (columbia) wilde type (1,2) or NPQ4 (3,4) was ground to fine powder in liquid nitrogen with a small plastic grinder and further homogenized in 200 ul of 1x Sample Loading Buffer (12 % glycerol, 60 mM Tris-HCl pH 6.8, 2.2 % SDS, 0.04 % bromophenol blue, 1.2 % beta-mercaptoethanol). Samples were heated at 95C for 1.5 minute and spun 30 seconds at 12k rpm. 10 ul of total protein extract was loaded onto BoltTM 4-12 % Bis-TrisPlusGels (Invitrogen) and run for 40 min. at 165 V and transferred to nitrocellulose in mini Bolt module for 1 h at 10V. Blot was blocked in 5 % nonfat dry milk in TBST (NaCl 137 mM, KCl 2.7 mM, Tri base 19 mM) and incubated with primary antibodies at 1: 1000 dilution for 1 hour at RT. After 4x5 minute wash in TBST, secondary antibody incubation (goat anti-rabbit IgG HRP conjugated, Agrisera AS09 602) at a dilution of 1: 10 000 for 1 h was follwed by 4x5 min. washes. Blots were well drained and incubaed briefly with PierceSuperSignalWest Pico Chemiluminescent Sustraste before exposure to ImageQuant ccd camera

Western blot detection of PsbS in Arabidopsis, Barchypodium and rice

10 µL of total protein extracted freshly from Arabidopsis thaliana (A), Brachypodium distachyon (B) and Oryza sativa (R) with 1X Laemmli Buffer (63 mM Tris-HCl pH 6.8, 10% (w/v) glycerol, 2% SDS and Bromophenol Blue q.b./1 pick) diluted to 1:2 and denatured with 25 mM DTT at 95ºC for 4 min, were resolved on a 10 % SDS-PAGE and blotted 1h to PVDF membrane (pore size of 0.45 μm, GE Healthcare), using wet transfer. Blot was blocked with Blocking solution containing 5% milk in TBS-T, for 1h/RT with agitation. Membrane was incubated with the primary antibody at a dilution of 1:2000 in Blocking solution containing 5% milk in TBS-T, for 1h/RT with agitation in TBS-T. The antibody solution was removed, and the membrane was washed 3 times for 10 min in TBS-T at RT with agitation. The membrane was then incubated in the secondary antibody (anti-rabbit IgG, horse radish peroxidase conjugated) diluted to 1:20 000 in Blocking solution containing 5% milk in TBS-T, for 1h/RT with agitation. After incubation with the secondary antibody, membrane was washed 6 times for 5 min in TBS-T at RT with agitation and developed for 1 min with Agrisera ECLSuperBright. Exposure time was 10 seconds.

Western blot analysis of PsbS and LHCSR proteins from dark-adapted (D, 30 min), light-treated (L, 2500 µmol photons m?2 s?1, 30 min) and post-dark-recovery chloroplasts (R, 1 h) isolated from B. corticulans. Samples were analysed by immunoblotting with an anti-PsbS (a), anti-LHCSR3 (b) and anti-LHCSR1 antibodies (c). Control samples are dark-adapted S. oleracea (a) and C. reinhardtii chloroplasts (b, c). Note that B. corticulans and S. oleracea samples have been probed against anti-PsbS antibody in the same membrane. The separation between lanes is only due to the presence of different samples between those presented of S. oleracea and B. corticulans (a). The ? subunit of ATP synthase (ATP-B) was used as loading control. 10 µg of Chl was loaded in each lane

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%).

PSII  available antibodies against Photosystem II proteins

Plant protein extraction buffer



The 22 kDa PsbS protein of photosystem II functions in the regulation of photosynthetic light harvesting. Along with a low thylakoid lumen pH and the presence of de-epoxidized xanthophylls, PsbS is necessary for photoprotective thermal dissipation of excess absorbed light energy in plants, measured as non-photochemical quenching of chlorophyll fluorescence. Synonymes: NPQ4 (NONPHOTOCHEMICAL QUENCHING).
