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).,For detection of PIF5 please use the most sensitive detection reagent
PIF5 (Phytochrome interacting factor 5) is a transcription factor negatively involved in the photochrome B signaling pathway, modulating PHYB at a posttranscriptional level. Replacement protein names :AtbHLH65, bHLH65, bHLH065, basic helix-loop-helix protein 65, photochromin interaction factor 1221123-like 6, PIL6, photochromin interaction factor like 6, transcription factor en103.
