Immunogen: 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.

Samples:
1 - 10 ug of 4 days old of wild-type Arabidopsis thaliana seedlings extract

10 µg/well of total protein extracted from fresh 4 days old of Arabidopsis thaliana whole seedling. Exact buffer components were: (50 mM Tris–HCl pH 7.5, 10% glycerol, 150 mM NaCl, 10 mM MgCl2, 5 mM EDTA, 5 mM DTT, 0.5% (v/v) Triton X-100, and 1 × protease inhibitors) and denatured with 4X SDS sample loading buffer (200 mM Tris-HCl (pH 6.8). 8% SDS (sodium dodecyl sulfate). 0.4% Bromophenol blue. 40% glycerol) at 95°C 10 min. Samples were separated in the RT on 15 % SDS-PAGE and blotted for 0.5 h to PVDF (pore size of 0.2 um), using: semi-dry at room temperature. Blot was blocked with 5 % milk for: 1h/RT with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2 000 at 4°C with agitation overnight. 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 RT with agitation. Blot was incubated in matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated AS09 602 Agrisera) diluted to 1: 50 000 for 2 h/RT with agitation. The blot was washed as above and developed with a following chemiluminescent detection reagent: AS16 ECL-N-10 AgriseraBright (mid picogram). Exposure time was 5 seconds.Courtesy of Dr .Duorong Xu, LMU München, Germany
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.

Open PublicationStepwise 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

Additional information: Antibody format is a total IgG fraction, which means that it is a pool of polyclonal antibodies obtained by purification of serum on Protein G, not on a specific antigen column.
Additional information (application): Protein is processed into mature form (Jansson 1999). - Background

Background: 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. - Product Citations

It is working on Oriza Sativa.Soo Yeon Ko | 2019-11-18The antibody is working on Oriza Sativa. We used isolated 2ug thylakoid membrane and can get a band (1:5000 dilution) clearlyK. Browning | 2015-07-21Works well with Arabidopsis total and chloroplast extracts. Some cross reactivity in total extracts with bands ~38 and ~75 kDa with overnight incubation in cold, but no cross reactive bands for chloroplast extracts when incubated only 1-2 hr at RT.Maciej Garstka | 2009-03-19specific to pea, bean and rye
