| 摘要 |
The invention relates to a method for detecting several different chromosomes or DNA regions in a cell in order to provide evidence for structural chromosomal aberrations, wherein the chromosomal aberrations have at least two breaking point regions within a chromosome, on the basis of directly or indirectly labeled nucleic acid fragments (probes), wherein: a first probe labeled with label A (probe A) and a second probe labeled with label B (probe B) flank a breaking point region 1, and form the fusion signals A-B; and two probes, a third and a fourth, each labeled with a label C (probes C), flank a breaking point region 2, and form the fusion signals C-C, wherein the above-mentioned fusion signals change in the event of a chromosomal aberration to fusion signals A-C and to fusion signals B-C. |
