Topoisomerase Type IIa Nuclear Extraction/Assay Kit Product Description

This Kit is designed to allow a researcher to prepare a nuclear extract enriched for type II topoisomerase (topo II) activity and topo II polypeptide.  The appropriate assay buffer specific for topo II is included.  This kit is suitable for most animal cell lines growing in vitro but is optimized for human and rodent species. This Kit also allows the investigator to quantify topo II activity in any given cell line. This Kit also provides the end user a source of enzyme for preliminary drug screening or HTS.
