KLH-conjugated synthetic peptide chosen from Arabidopsis thaliana PsbR UniProt: P27202, TAIR: At1g79040

14 | 10 kDa

Chlamydomonas reinhardtii, Hordeum vulgare, Synechococcus sp. PCC 7942

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% 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: 50 000 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) 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 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). Exposure time was 1 second.

This product can be sold containing proclin if requested

PsbR protein is found in plant Photosystem II and anticipate to play a role in water oxidation, yet the physiological significance of PsbR has remained obscure.
