  • Application Examples
  • Western blot using anti-Lhcb1, phosphorylated antibodies

    1,5 µg of chlorophyll from Zea mays, mesophyll (1) and bundle sheath (2), Panicum miliaceum, mesophyll (3) and bundle sheath (4), Echinochloa crus-galli, mesophyll (5) and bundle sheath (6), Arabidopsis thaliana (7), Pisum sativum (8) chloroplasts extracted with 0.4 M sorbitol, 50 mM HEPES NaOH, pH 7.8, 10 mM NaCl, 5 mM MgCl2 and 2 mM EDTA were loaded to lanes. 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% BSA for 2h at room temperature (RT) with agitation. Blot was incubated in the primary antibody Anti-Lhcb1-P (LOT 2201) at a dilution of 1: 10 000 in 1% BSA in TBS-T overnight at 40C 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, LOT 2106) diluted to 1: 20 000 in  1 % BSA 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 153 seconds.

    1 µg of thylakoid membranes isolated from Arabidopsis thaliana wilde-type and mutants were solubilized with 3X LB (6 M urea, 12% SDS, 30% glycerol, 100 mM DTT, 150 mM Tris pH7.0, 0.8% Comassie G-250). 1 µg of total chlorophyll was loaded and separated on 16% SDS-PAGE, and then blotted for 2 h onto nitrocellulose membrane. Blots were blocked with milk powder for 2 h and then incubated in the primary antibody solution, at a dilution of 1: 5 000/2.5 h, RT incubation, which was then decanted and the blot was washed 3 times for 5 min in TBST. Membrane was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:10 000 in for 1h, followed by washing steps as above. All the steps fallowing transfer were performed in room temperature (RT) with agitation. Membrane was developed for 5 min with ECL according to the manufacturer’s instructions and recorded using FujiFilm CCD camera with 30 s increment time for around 5 min.

  • Background
  • Background:

    The major light-harvesting antenna complex II (LHCII) in photosynthetic 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. Lhcb1 is the most abundant chlorophyll a/b-binding protein in eukaryotic phototrophs and often is coded by several nuclear genes.

    We always use this antibody when we check the Lhcb1-p band in Western blot (1:10000 dilution) . It is also working on Oriza Sativa. We used it with isolated 2ug thylakoid membrane.

    The antibody is working on Oriza Sativa and Arabidopsis thaliana. We used it with isolated 2ug thylakoid membrane and could get the band (1:5000 dilution)

    These antibodies worked very well with thylacoid preparations from Arabidopsis and Barley. Only one spesific thing should be noted about the protocol is that blotting with the primary antibody should be continued overhight at 4.
