Overview research topics and techniques 1.basic technology for DNA and RNA work - biochemistry of collagen 2. karyotyping 3. FISH : detection of DNA targets in cytological preparations) one or two DNA targets • CGH (comparative genomic hybridisation) : detection of • genomic imbalances of chromosomal regions • fiber FISH : FISH on stretched chromatin fibers • FICTION : FISH combined with immunophenotyping • M-FISH (multicolor FISH) : 24 or more DNA targets
