5 µg of total protein from (1) Arabidopsis thaliana leaf extract, (2) Synechococcus sp. PCC 7942 , (3) Hordeum vulgare leaf extract, (4) Physcomitrella patens, (5) Pisum sativum, (6) Zea may were extracted with Agrisera Protein Extraction Buffer PEB and separated on 4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to nitrocellulose OSMONICS. Blots were blocked immediately following transfer in 2% blocking reagent in 20 mM Tris, 137 mM sodium chloride pH 7.6 with 0.1% (v/v) Tween-20 (TBS-T) for 1h at room temperature with agitation. Blots were incubated in the primary antibody at a dilution of 1: 10 000 for 1h at room temperature with agitation. 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 room temperature with agitation. Blots were incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, from Agrisera, AS09 602) diluted to 1:50 000 in 2% blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with che,iluminescent detection reagent according to the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad). Exposure time was 30 seconds.

Photosystem I (PSI) of chloroplasts is a multisubunit membrane-protein complex that catalyzes the electron transfer from the reduced plastocyanin (or cytochrome c6) in the thylakoid lumen to the oxidized ferredoxin (or flavodoxin) in the chloroplast stroma. PsaB is a core protein of PSI complex. Synonymes: Photosystem I P700 chlorophyll a apoprotein A2, PSI-B
