BSA-conjugated synthetic peptide derived from a highly conserved sequence of Lhcb3 proteins from angiosperms (monocots and dicots) and gymnosperms, including Arabidopsis thaliana Lhcb3 UniProt: Q9S7M0,TAIR:AT5G54270. This sequence is highly conserved even in Ginko biloba and one of the major LHCII-forms of Physcomitrella patens.

From 1 μg to 8 μg of chlorophyll from Arabidopsis thaliana chloroplasts extracted with 0.4 M sorbitol, 50 mM Hepes NaOH, pH 7.8, 10 mM NaCl, 5 mM MgCl 2 and 2 mM EDTA were loaded to lanes. Samples were denatured with Laemmli buffer at 75 0 C 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 for 2h at room temperature (RT) with agitation. Blot was incubated in the primary antibody Anti-Lhcb3 (LOT 1901) at a dilution of 1: 2000 in 1% milk in TBS-T overnight at 4 0 C with agitation. 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 HRP conjugated, from Agrisera, AS09 602) diluted to 1:20 000 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% H 2O2 in 0.1 M Tris- HCl, pH 8.5. Exposure time in ChemiDoc System was 240 seconds.

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
The major light-harvesting antenna complex II (LHCII) in photsynthetic eukaryotes is located in the thylakoid membrane of the chloroplast. It is a heterotrimeric complex formed by up to 3 different individual subtypes of chlorophyll a/b-binding proteins: Lhcb1, Lhcb2, and Lhcb3. While Lhcb1 and Lhcb2 are quite similar and regularily present in multiple gene-copies, the Lhcb3 protein differs in pigment-composition and molecular size and often is coded by only a single gene. Lhcb3 seems not to be present in the mobile LHCII trimers involved in state 1-state 2 transitions.
A molecular characterisation of the LHCII proteins can be found in Caffarri et al. (2004) A Look within LHCII: Differential Analysis of the Lhcb1−3 Complexes Building the Major Trimeric Antenna Complex of Higher-Plant Photosynthesis. Biochemistry 43 (29): 9467–9476.
