1.0-4.5 µg of chlorophyll from Coccomyxa subellipsoidea cells were loaded to lanes. Samples were denatured with Laemmli buffer at 75°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 in TBS for 2h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 2000 overnight at 4°C with agitation in 1% milk in TBS-T. 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 horse radish peroxidase 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 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 115 seconds.

Lhcb5 is one of the 3 minor, highly conserved chlorophyll a/b-binding proteins associated with Photosystem II in plants and algae. As a part of the inner light-harvesting antenna it has been sugested to regulate (together with Lhcb4 and Lhcb6) the energy flow from the outer LHCII antenna to the PSII reaction center.
