high-sensitivity detection of incorporated

                       This report describes an improved immunochemical
procedure to stain cells in suspension for incorporated bromodeoxyuridine
                       (BrdUrd) and total DNA content. The procedure consists
of five steps: chromatin proteins are extracted by treating with 0.1 M
                       HCl and 0.7% Triton X-100 to facilitate DNA denaturation
and to minimize nonspecific staining; cellular DNA is denatured by
                       heating to 100 degrees C in distilled water; BrdUrd in
single-stranded DNA (ssDNA) is stained using an immunochemical
                       procedure; autofluorescence is reduced using sodium
borohydride (NaBH4); and DNA is stained with the fluorescent dye
                       propidium iodide. With this procedure, the BrdUrd
incorporated by CHO cells during periods as short as a few seconds can be
                       detected using flow cytometry. In addition, the
stoichiometry of the immunofluorescent staining procedure is high.
