β¦ Synopsis
The variation of the fluorescence intcnsity of olivomycin-stained yeast cells as a function of the concentrdtion of olivomycin, NaCI, and MgCI, in the staining solution was studied.
The best results were obtained when the staining solution contained 100 pg olivomycin/ml, 40 mM MgC12, and 1 M NaCI. A staining time of 12 min was sufficient for proper staining.

## Abstract An immunofluorescence method for monitoring DNA synthesis in single cells has been developed for flow cytometry. With antiserum which is specific for 5βbromodeoxyuridine (BrdUrd) and a second fluorescent label, BrdUrdβincorporation pulses of 30 min are detectable. The fluorescence inten
Cell division cycle (cdc) mutants of Schizosaccharomyces pombe are arrested at specific points in the cell cycle when grown at restrictive temperature. Flow cytometry of such cells reveals an anomalous increase in the DNA fluorescence signal, which represents a problem in experiments designed to det
