Western blot using anti-PIF4 rabbit antibodies

5-20 µg of Arabidopsis thaliana nuclear proteins were extracted according to Gendrel et al. 2005. Samples were denatured with SDS page loading buffer at 90°C for 5 min, separated on 12% SDS-PAGE and then blotted 1h to PVDF using wet transfer. Blot was blocked with 5% milk 1h at RT with agitation and then It was incubated with the anti-PIF4 antibody at a dilution of 1:1000 in TBS-T ON at 4°C in agitation. The antibody solution was decanted and the blot was rinsed briefly with TBS-T, then washed 3 times for 15 min in TBS-T at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated) diluted to 1:25 000 in TBS-T for 1h/RT with agitation (Agrisera AS09 602). The blot was washed as above and developed with chemiluminescent ragent. Exposure time was 30 min.

Additional information

Additional information

PIF proteins are very unstable, therefore special precautions should be taken during extraction and whole procedure should be performed in the dark and with as little light as possible (green light only).

Extraction of PIF proteins is described in Shen et al. (2007).

This product can be sold containing ProClin if requested.
