Comparison of different labelling index formulae used on bromodeoxyuridine-flow cytometry data
The essence of the bromodeoxyuridine (BrdUrd)-flow cytometry (FCM) technique is that cells are labelled with the thymidine analogue BrdUrd. They are then allowed to progress through the cell cycle in a BrdUrd-free environment during the postlabelling time period. At a postlabelling time shorter than the length of the S phase (Ts), cells are fixed and prepared for FCM-mediated analysis of BrdUrd an
