S-phase evaluation with bromodeoxyuridine in lymphocytes from cattle infected with bovine leukemia virus (BLV).
Bromodeoxyuridine (BrdUrd), an analogue of thymidine, can be detected by means of monoclonal antibodies and utilized as a marker of the S-phase. In this paper a determination of the S-phase in BLV+ cattle with lymphocytosis has been performed by incorporating bromodeoxyuridine in the DNA. This evaluation was compared to the DNA content, demonstrating that i) bromodeoxyuridine incorporation is a reliable marker of S-phase in BLV+ cattle with lymphocytosis and ii) cytofluorimetry is the method of choice, together with immunocytochemistry, to demonstrate bromodeoxyuridine incorporation.
