product information

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. Lhcb2 is often coded by several nuclear genes and is found together with Lhcb1 within the mobile LHCII trimers involved in state1-state2 transition.


KLH-conjugated synthetic peptide: RRT*VKSTPQS, where T* indicates phospho-Thr

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum
Format Lyophilized
Quantity 25 ĩg
Reconstitution For reconstitution add 25 ĩl of sterile water.

store lyophilized/reconstituted at -20°C; once reconstituted make aliquots to avoid repeated freeze-thaw cycles. Please, remember to spin tubes briefly prior to opening them to avoid any losses that might occur from lyophilized material adhering to the cap or sides of the tubes.

application example

western blot using anti-phosphorylated Lhcb2 antibodies

1 ug of thylakoid membranes isolated from Arabidopsis thaliana wild-type and respective 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 (AS01 004, 1: 5 000) for 2.5 h, 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.
