EdU (5-ethynyl-2′-deoxyuridine) is a nucleoside analog to thymidine and is incorporated into DNA during active DNA synthesis. In contrast to BrdU assays, the EdU-Click Assays are not antibody based and therefore do not require DNA denaturation for detection of the incorporated nucleoside. Instead, the Baseclick EdU-Click Assays utilize click chemistry for detection in a variety of dye fluorescent readouts. Furthermore, the streamlined detection protocol reduces both the total number of steps and significantly decreases the total amount of time. The simple click chemistry detection procedure is complete within 30 minutes and is compatible with multiplexing for content and context-rich results.
