  • Application example

    Western blot using anti-cAPX antibodies on tomato samples


    40 µg of total protein from Solanum lycopersicum extracted with Extraction buffer (1x Hepes buffer, cOmplete Mini protease inhibitor cocktail (1 tablet/10ml), 5mM DTT) and denatured with 1x SDS-loading buffer at 95°C for 5 min. Samples were separated on 12 % SDS-PAGE and blotted 1h to PVDF using dry transfer. Blots were blocked with 5% milk in TBST for 45 min with agitation. Blot was then washed once with TBST, and then incubated in the primary antibody a-cAPX at a dilution of 1:2000 ON/4°C with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in Agrisera matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602) diluted to 1:5000 in for 30min/RT with agitation. The blot was washed as above and developed for 2 min with chemiluminescence detection reagent. Exposure time was set to automatic.

    Western blot using anti-cAPX antibodies on A.thaliana samples

    20 µg of total protein from Arabidopsis thaliana total (1), soluble (2) and membrane (3) fractions were prepared according to Planas-Marquès et al. (2016)     and denatured with 1x SDS-loading buffer at 95°C for 5 min. Samples were separated on 12 % SDS-PAGE and blotted 1h to PVDF using dry transfer. Blots were blocked with 12 % milk in TBST for 45 min with agitation. Blot was then washed once with TBST, and then incubated in the primary antibody a-cAPX at a dilution of 1:10 000 ON/4°C with agitation. The antibody solution was decanted and the blot was rinsed briefly twice, then washed once for 3 times for 5 min in TBS-T at RT with agitation. Blot was incubated in Agrisera matching secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, AS09 602) diluted to 1:5000 in for 30min/RT with agitation. The blot was washed as above and developed with chemiluminescent detection reagent.  Exposure time was set to automatic.

  • Additional Information
  • Additional information: Total IgG concentration is 3 µg/µl
  • Background
  • Background:

    Ascorbate peroxidase (APX) is the enzyme catalyzing the ascorbate-dependent reduction of hydrogen peroxide. Ascorbate (AA) plays a key role in defense against oxidative stress and is particularly abundant in fruits and photosynthetic tissues. AA is found in every compartment of the plant cell including the apoplast.

    I used it for Citrus sinensis. I had excellent resolution of the cAPX bands. It also appears the bands of tylAPX and stromal APX wich I had to diferenciate.
