Plant/Algal cell antibodies / Photosynthesis / PSII (Photosystem II)

product information

The PsbO protein is an extrinisic subunit of the water splitting photosystem II (PSII) complex. The protein is exposed on the luminal side of the thylakoid membrane, and is hihgly conserved in all known oxygenic photosynthetic organisms. Alternative names of PsbO1 include  33 kDa subunit of oxygen evolving system of photosystem II, OEC 33 kDa subunit, 33 kDa thylakoid membrane protein, manganese-stabilizing protein 1 and for PsbO2 33 kDa subunit of oxygen evolving system of photosystem II,  OEC 33 kDa subunit, 33 kDa thylakoid membrane protein,   manganese-stabilizing protein 2.

N-terminually located peptide chosen from Arabidopsis thaliana PsbO1 At5g66570 and 2 proteins At3g50820

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

2 µg of total protein from (1) Arabidopsis thaliana leaf, (2) Horderum vulgare leaf ), (3) Chlamydomonas reinhardtii total cell , (4) Synechococcus sp. 7942 total cell were all extracted with PEB (AS08 300) and separated on  4-12% NuPage (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following transfer in 2% ECL Advance blocking reagent (GE Healthcare) 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 Abcam) diluted to 1:50 000 in 2% ECL Advance blocking solution for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with ECL Advance 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).
