product information
Background PIF5 (Phytochrome interacting factor 5) is a transcription factor which acts negatively in the phytochrome B signaling pathway and regulates PHYB at post-transcriptional level. Alternative protein names: AtbHLH65, bHLH65, bHLH065, Basic helix-loop-helix protein 65, PHYTOCHROME INTERACTING FACTOR 3-LIKE 6, PIL6, Phytochrome interacting factor-like 6, Transcription factor EN 103.

KLH-conjugated synthetic peptide derived from Arabidopsis thaliana PIF5, UniProt: Q84LH8, TAIR: AT3G59060

Host Rabbit
Clonality Polyclonal
Purity Affinity purified serum

Additional information

PIF proteins are not that stable, therefore special precautions should be taken during extraction and whole procedure should be performed in as little light as possible (light green light).

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

application example

western blot using anti-PIF5 antibodies

10 µg of total protein from 4 day old dark grown Arabidopsis thaliana seedligns extracted with hot buffer (Shen et al., Plant Cell. 2008;20(6):1586-602) were separated on 8 % SDS-PAGE and blotted 1h to PVDF using semi-dry. Blots were blocked with the blocking buffer from Protein Detector LumiGLO western blotting kit (KPL, Cat: 54-12-50) for 1h at room temperature (RT) with agitation. Blot was incubated in the primary antibody at a dilution of 1: 1 000 for overnight at 4 degree with agitation. The antibody solution was decanted and the blot was for 3 times for 5 min in the washing buffer from the same kit at RT with agitation. Blot was incubated in secondary antibody (anti-rabbit IgG horse radish peroxidase conjugated, (AS09 602 from Agrisera) diluted to 1:25 000 in for 2h at RT with agitation. The blot was washed as above and developed for 5 min with ECL (femto from life technology) according to the manufacturer's instructions. Exposure time was 2 minute.

Higher % of a gel can separate better cross-reacting band and PIF5 protein.
