The Poseidon Whole Chromosome probes hybridize to unique sequences spanning the entire length of the target chromosome.

These probes are derived from flow-sorted or microdissected chromosomes and provide accurate coverage with excellent signal specificity and high fluorescent intensity. Some minor cross-hybridization may occur at the short arm of acrocentric chromosomes (13, 14, 15, 21 and 22) and in the pseudo-autosomal regions of chromosome X and Y.
