Abstract: | A technique is described for labeling mammalian chromosomes in vivo with BUdR. Rats and mice are given BUdR by tail vein infusion over a 24-h period at a concentration of 25 μg/g wt/h. Metaphase cells that have gone through two or three cycles of DNA synthesis reveal characteristic differential chromatid fluorescence after staining with Hoechst dye. Sister chromatid exchanges can then be easily detected in these cells. |
