Custom PNA synthesis 🧬: LifeTein provides custom PNA oligos, unlabeled (50nmole) or labeled (25nmol) by fluorescent dyes or other modifications. The PNA oligos can be conjugated to peptides for additional functionality. PNA oligomers can be labeled at 5' and/or 3' end. These labels are available upon request: fluorophores including FAM, FITC, Alexa Fluor dyes, Atto dyes, Cyanine dyes (cy3, cy5, cy7), QSY9, Pyrene, Dylight, quenchers (BHQ, Dabcyl), Acridine, Butyric acid, Alkyne (DBCO or Pentynoic acid), Azide, Biotin, photocleavable biotin, Maleimide, Myristol, Palmitic acid, et al. Contact us if your modification is not on the list.

PNA FISH Probe

  • PNA has an electrically neutral backbone. This key feature of high specificity enables rapid hybridization with just a small amount of PNA probe without significant background signal. So PNA is very efficient and useful in applying to FISH (fluorescent in situ hybridization) at low concentrations.
  • C-rich probe (repeats of CCCTAA): TelC is a C-rich telomere probe for a leading strand (repeats of TAACCC).It is used to detect human, mouse, rat chromosomes.
  • G-rich probe (repeats of TTAGGG): TelG is a G-rich telomere probe for lagging strand (repeats of TTAGGG).
  • Pan-centromere probe: Cent probe is specific for human alpha satellite centromere and does not react to the mouse. The sequence of the probe is AAACTAGACAGAAGCAT.
  • CENPB probe: CENPB probe is a binding site for centromere protein B (CENP-B). The probe sequence is ATTCGTTGGAAACGGGA.
  • CAG repeat probes: (CAG)5-Cy3 and (CAG)5-Cy5
