    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.

  • Additional Information
  • Additional information:
    PR-1 protein is present in very low amonts in non-induced plant material.

    Overnight antibody incubation is not recommended.

    This product can be sold containing Proclin if requested.
    Additional information (application): Re-using of antibody solution is not recommended, It will contribute to incrteased background signal
  • Background
  • Background:

    Pathogenesis-related protein 1 (PR-1), small antimicrobial protein which acts as a marker of plant immune signaling and is partially responsible for acquired pathogen resistance. Induced by INA, salicylic acid and pathogen infection.

    This antibody works very well, very strong signal and no background. Our lab used this antibody in many experiments to show defense induction by pathogens and PAMPs in Arabidopsis, e.g.

    We have excellent results with this antibody- a strong signal with low background on Arabidopsis total protein extracts. Recommended.
