PIF4 | Phytochrome interacting factor 4 (rabbit antibody)

KLH-conjugated peptide derived from Arabidopsis thaliana PIF4, UniProt: Q8W2F3, TAIR:AT2G43010

Application example




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.
