Application example

quantitative western blot using recombinant PR-1 protein

Recombinant PR-1 protein standard 0.05 pmol (1),  0.1 pmol (2), 0.15 pmol (3), 0.2 pmol (4), and 0.3 pmol (5) was loaded in each lane. Protein separation was done using NuPage 4-12% Tris-Bis gel (Invitrogen) LDS-PAGE and blotted 1h to PVDF. Blots were blocked immediately following transfer in 2-2.5 % RPN2125 (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 anti-PR-1 antibody at a dilution of 1: 10 000 in blocking reagent 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 1:25 000 in TBS-T for 1h at room temperature with agitation. The blots were washed as above and developed for 5 min with chemiluminescent detection reagent in extreme low femtogram range, according 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 minute.



Immunolocalization using anti-PR-1 antibodies

Immunostaining of Arabidopsis thaliana seedlings treated with 250 µM SA for 120 minutes for induction of PR- gene expression (right panel) or control without SA (left panel). Steps involved: fixation: in 2 % formaldehyde in MTSB buffer for 30 minutes at 37 °C; washing with water, hydrophilization with methanol; cell wall digestion: 5-7 minutes, 0.25% Dricelaze, 0.1 % Macerozyme in 5 mM MES buffer, pH5.2; cell wall permeabilization: 10 % DMSO/3 % NP40 in MTSB buffer; primary antibody incubation: dilution 1: 200 in MTBS buffer for 3 h at RT; secondary antibody incubation: dilution 1: 1000 at RT for 1 h, goat-anti rabbit IgG Alexa 488 conjugated antibody.
