Samples of isolated thylakoids containing 3 µg of chlorophyll were denatured with Laemmli buffer (1 vol : 1 vol) at 75 °C for 5 min. Denatured samples containing 1 µg of chlorophyll were loaded in the gel wells, separated on 12% SDS-PAGE gels and blotted for 45 min at 100 V to PVDF membrane using wet transfer. Blot was blocked with 5% milk in TBS-T for 60 min at room temperature (RT) with agitation. The blot was incubated with the primary antibody at a dilution of 1:500 in 1% Amersham™ ECL Prime Blocking Agent in TBS-T overnight at 4ºC with agitation. The antibody solution was decanted and the blot was washed 3 times for 5 min in TBS-T at RT with agitation. The blot was incubated using a secondary antibody (goat anti-rabbit IgG HRP conjugated, from Agrisera, AS09 602) diluted to 1: 25 000 in 1% milk in TBS-T for 1h at RT with agitation. The blot was washed 5 times for 5 min in TBS-T, 1 time for 5 min in TBS, 1 time for 5 min in 0.1 M Tris (pH 8.5), and developed for 4 min in substrates (0.188 mM coumaric acid, 1.25 mM luminol, 0.01% H2O2). Exposure time was 5 seconds in ChemiDoc scanner (BioRad).

Immunoprecipitation has been done using Immunoprecipitation kit from Roche, Cat.No. 11 719 386 001.
Protein is processed into mature form (Jansson 1999).
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.
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.
