PNA FISH Probes

PNA FISH probes hybridize to target DNA with high sensitivity and specificity mainly due to the electrical neutrality of its chemical structure. This trait enables PNA probes to be more efficient and useful in applying to FISH (fluorescent in situ hybridization) even at low concentrations. Hybridization occurs fast (within a couple of hours) and background noise is reduced significantly.

PNA Bio offers

telomere, centromere

, and CAG repeat probes as catalog items. If you need 
other target specific probes, we can provide a custom PNA probe synthesis service.

TelC is C-rich a telomere probe for a leading strand (repeats of TAACCC) and TelG is a G-rich telomere probe for lagging strand (repeats of TTAGGG). 
Both TelC and TelG PNA telomere probes work with human, mouse, and rat chromosomes.

CENPB probe is a binding site for centromere protein B (CENP-B), one of the major centromere-specific proteins. The probe sequence is ATTCGTTGGAAACGGGA, and it stains minor satellite of all human and mouse centromere except the Y chromosome.

Cent probe is specific for human alpha satellite centromere and does not react to the mouse.
  
The sequence of the probe is AAACTAGACAGAAGCAT.
