Previously, assays for sister chromatid segregation patterns relied on incorporation of BrdU and indirect methods to infer segregation patterns after two cell divisions. Here we describe a method to differentially label sister chromatids of murine cells and directly assay sister chromatid segregation patterns following one cell division in vitro and in vivo by adaptation of the well-established CO-FISH (chromosome orientation fluorescent in situ hybridization) technique. 5-bromo-2′-deoxyuridine (BrdU) is incorporated into newly-formed DNA strands, followed by photolysis and exonuclease digestion to create single-stranded sister chromatids containing parental template DNA only. Such single-stranded sister chromatids are differentially labeled using unidirectional probes to major satellite sequences coupled to fluorescent markers. Differentially-labeled sister chromatids in post-mitotic cells are visualized using fluorescence microscopy and sister chromatid segregation patterns can be directly assayed after one cell division. This procedure requires four days for in vivo mouse tissues, and two days for in vitro cultured cells.
