A protocol for the sensitive and quantitative detection of topoisomerase 1 activity using the rolling circle enhanced enzyme activity detection assay is described. The method allows detection of topoisomerase 1 activity from purified components or cell/tissue extracts. This protocol has wide-ranging applications in any field involving detection of enzymatic activity.
