PNA has very high specificity and sensitivity to target DNA mainly due to electrically neutrality of its chemical structure. This trait enables PNA probes to be useful for FISH (fluorescent in situ hybridization) study even at low concentrations.

When used with PNA probes for FISH, hybridization is fast with significantly reduced background noise that results in high signal to background noise ratio.
Panagene supplies PNA telomere probes to measure telomere size quantitatively with the following specification and prices.
