title: Measurement of T and B cell turnover with bromodeoxyuridine.
abstract: This unit describes two methods used to determine the rate of turnover of T and B cells in vivo. In each method, this is accomplished by administering 5-bromo-2'-deoxyuridine (BrdU), a thymidine analog, and measuring the rate at which cells become labeled with this DNA precursor during the S phase of the cell cycle. Cells that contain BrdU are then detected in vitro using fluorochrome-labelled anti-BrdU monoclonal antibody by flow cytometry. The unit includes an Alternate Protocol that may be useful in situations where the Basic Protocol proves incompatible with particular antibody-fluorochrome conjugates or other downstream staining procedures. Using this procedure, a wide range of antibody-fluorochrome combinations can be used.
