Types of FISH Probes

Slide 12

September 2011

There are 2 basic types of FISH probes: chromosome enumeration probes and locus specific probes. Chromosome enumeration probes attach to the centromeres of chromosomes and are used to determine how many copies of a chromosome are present in a cell. Locus specific probes are designed to attach to genes of interest, for example the P16 tumor suppressor gene or the HER2 oncogene, and are used to determine if a cell shows deletion or amplification of those genes.
