Class 1 histone deacetylases (HDACs) like RpdA have gained importance as potential targets to treat fungal infections. Here we present a protocol for the specific enrichment of TAP-tagged RpdA combined with an HDAC activity assay that allows in vitro efficacy testing of histone deacetylase inhibitors.
