Hydroxyurea-induced synchrony of DNA replication in the Kinetoplastida.


We have developed a reliable and reproducible method to induce synchrony of the DNA synthetic cycle in the Kinetoplastida. The method involves treatment of cultures with 20 mM hydroxyurea (HU) and fetal bovine serum. Both stationary-phase and exponential-phase cultures can be synchronized. However, in the case of exponential-phase cultures the population… (More)
