The specificity and sensitivity of the monoclonal antibody Ki-67 in identifying proliferating cell compartments was tested with the human promyelocytic leukemia cell line HL-60 using multi-parameter flow cytometry. While correlated measurements of DNA content and Ki-67 immunofluorescence indicated that the antigen was present in all phases of the cell cycle, reactivity with the antibody was highest in proliferating S and G2+ M cells. The analysis of the BrdU content of cells sorted on the basis of reactivity with Ki-67 showed a correlation between Ki-67 reactivity and BrdU uptake. In HL-60 cells induced to differentiate with dimethyl sulfoxide (DMSO), the loss of reactivity with Ki-67 paralleled the exit of cells from the cell cycle. This was not observed in DMSO-resistant HL-60 cells. These results validate the usefulness of the Ki-67 antibody for determining the proliferative stage of mammalian cells in culture.
