Abstract

The present invention relates generally to a method for identifying or distinguishing one type of cell from other cells within a population of cells. The present invention further provides the detection, monitoring and isolation of sub-populations cell types within a population of cells including a biological entity comprising such cell types. Kits, diagnostic agents and panels of nucleic acid probes for identifying and distinguishing cell types also form part of the present invention. The detection of particular cell types is based upon the use of a labelled probe that hybridizes to chromosomal DNA at the flanking sequences of a deletion. Alternatively two probes with distinguishable reporter molecules are used wherein only one probe is capable of hybridizing to chromosomal DNA in one cell type whereas both are capable of hybridizing to chromosomal DNA in another cell type. The methods are useful in the identification of cells with copy number variations, chromosomal deletions, additions or aberrations.
