title: Analysis of Cell Proliferation and Homeostasis Using EdU Labeling.
abstract: Determination of cellular proliferation and population turnover is an important tool for research on lymphoid cell function. Historically this has been done using radiolabeled nucleotides or nucleoside analogs, such as BrdU (5-bromo-2-deoxyuridine), that are incorporated into nascent DNA during S-phase. Recently, a new procedure was developed to label nascent DNA using EdU (5-Ethynyl-2-deoxyuridine). This new method overcomes limitations imposed by the procedure used to detect BrdU because EdU detection is based on an easily performed chemical reaction that does not require DNA denaturation, is quick and reproducible, and has a superior signal-to-noise ratio. This technique offers a wide range of opportunities to analyze cellular proliferation, population homeostasis, and cell marking procedures.
