Kits for Characterization of Chromosomal Inversions Using Probes
A kit for the characterization of chromosomal inversions using single-stranded probes that are either all identical or all complementary to a single-stranded chromatid is described. Reporter species are attached to oligonucleotide strands designed such that they may hybridize to portions of only one of a pair of single-stranded sister chromatids which may be prepared by the CO-FISH procedure. If an inversion has occurred, these marker probes will be detected on the second sister chromatid at the same location as the inversion on the first chromatid. The kit includes non-repetitive probes that are either all identical or all complementary to at least a portion of a target DNA sequence of only one DNA strand of only one chromatid and may in some embodiments include reagents suitable for performing CO-FISH and/or reagents for hybridizing the probes to the target DNA sequence.
