Chromatin profiling assays enable the mapping of protein-DNA interactions that influence chromatin modeling and gene expression.
Over the years, Chromatin ImmunoPrecipitation (ChIP) assays became the gold-standard for studying transcription factor–DNA binding interactions, nucleosome dynamics, and epigenetics (ex. histone post-translational modifications (PTMs)). This post aims at introducing the latest evolution of ChIP assays: CUTANA™ CUT&RUN and ChIC assays.
Over the last years, ChIP experts express the need for more sensitivity, faster protocols, and more reproducible results (and ideally starting from less starting cellular material). These expectations led to the emergence of new experimental antibody-based experimental approaches like Chromatin ImmunoCleavage (ChIC) assays, and Cleavage Under Targets and Release Using Nuclease (CUT&RUN) methods.
