The sequence of the Alexa 647-labeled centromere probe ATTCGTTGGAAACGGGA is 5' labeled by the Alexa 647 fluorescent Dye. The sequence is human specific.
PNA sequences are electrically neutral DNA/RNA analogs. The uncharged backbone enables rapid hybridization and improved stability compared to their DNA/RNA counterparts. Thanks to their high specificity for their target, small amounts are sufficient to give high signal-to-noise results. PNA FISH Centromere probes are recommended for tracking chromosome aberrations in the centromere such as trisomy and polysomy. Sequence break can be clearly detected.
