| Abstract: | Classical cytogenetics is often tedious and many efforts have been made to develop other methods of chromosome analysis, among which flow karyotyping has recently emerged. Although less efficient than banding techniques to identify each chromosome, flow cytometry offers the opportunity of analyzing large quantities of chromosomes at a very high rate, resulting in a flow karyotype. Even if the initial aim of this technique, namely clinical diagnosis, has not been reached, another major application has emerged, namely chromosome sorting. This method is unique for isolating a set of purified chromosomes from most cells grown in culture in sufficient amount to perform experiments using molecular biology techniques. Significant results have been already obtained either through the construction of chromosome-specific libraries or in the assignment of DNA probes to particular sorted chromosomes. |
