Chromatin Affinity Purification (ChAP) from Arabidopsis thaliana Rosette Leaves Using in vivo Biotinylation System
2018
Weronika Sura | Piotr Ziolkowski
Chromatin Affinity Purification (ChAP) is widely used to study chromatin architecture and protein complexes interacting with DNA. Here we present an efficient method for ChAP from Arabidopsis thaliana rosette leaves, in which in vivo biotinylation system is used. The chromatin is digested by Micrococcal Nuclease (MNase), hence the distribution of nucleosomes is also achieved. The in vivo biotinylation system was initially developed for Drosophila melanogaster (Mito et al., 2005), but the presented protocol has been developed specifically for Arabidopsis thaliana (Sura et al., 2017).
