product information
Background

PsbB (CP47) is a chlorophyll-binding protein located in the membrane, where it serves as the core antenna of Photosystem II.

Immunogen

KLH-conjugated synthetic peptide derived from available plant, algal and cyanobacterial PsbB sequences including Arabidopsis thaliana AtCg00680, Hordeum vulgare P10900, Oryza sativa P0C364, Synechocystis PCC 6803 P05429

Host Rabbit
Clonality Polyclonal
Clone
Purity Serum
Format Lyophilized
Quantity 50 µl
Reconstitution For reconstitution add 50 µl of sterile water.
Storage 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.
Tested applications Western blot (WB)

application example

2 µg of total protein from (1) Arabidopsis thaliana leaf extracted with PEB (AS08 300), (2) Horderum vulgare leaf extracted with PEB (AS08 300), (3) Chlamydomonas reinhardtii total cell extracted with PEB (AS08 300), (4) Synechococcus sp. 7942 total cell extracted with PEB (AS08 300), (5) Anabaena sp. total cell extracted with PEB (AS08 300) were 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: 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, recommended secondary antibody AS09 602) 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 the manufacturers instructions. Images of the blots were obtained using a CCD imager (FluorSMax, Bio-Rad) and Quantity One software (Bio-Rad).

 

Western blot of anti-PsbB antibody

application example

0.2 µg of chlorophyll from (4,5) Arabidopsis thaliana leaf extracted with PEB (AS08 300), (1) 500 fmol of PsbB protein standard, (2) 200 fmol of PsbB protein standard, (3) 75 fmol of PsbB protein standard were 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.
