Product Description

A probe for DNA synthesis in vivo that is less toxic than both EdU and BrdU. Ideally suited for metabolic DNA labeling when prolonged cell survival and undisturbed cell cycle progression are required.

Application：

F-ara-EdU (2’-deoxy-2’-fluoro-5-ethynyluridine) is a synthetic analog of thymidine used to study de novo DNA synthesis and cell proliferation. It is a less cytotoxic alternative for BrdU (5-Bromo-2’-deoxyuridine) and EdU (5-Ethynyl-2’-deoxyuridine).
F-ara-EdU incorporates into replicating DNA during the S-phase of the cell cycle instead of natural thymidine. Metabolic incorporation of F-ara-EdU into DNA can be detected by copper-catalyzed click reaction with fluorescent or biotin-labeled azides.
In contrast to EdU, F-ara-EdU causes little or no cellular arrest or DNA synthesis inhibition. Therefore, F-ara-EdU is ideally suited for pulse-chase experiments aimed at birth-dating DNA in vivo and long-term cell survival estimation.
