We report the application of the arsenical complex FlAsH-EDT2 for the identification of oligonucleotide sequences. We designed PNA sequences conjugated to either a tetracysteine motif and to split tetracysteine sequences, that are recognized by FlAsH. The effect of conjugation of the PNA to the tetracysteine peptide and RNA hybridization on the fluorescence of the arsenical complex has been investigated. The reconstitution of the tetracysteine motif, starting from 15-mer PNAs conjugated to split tetracysteine sequences and hybridized to a complementary oligonucleotide was also explored.bject]

Abstract
We report the application of the arsenical complex FlAsH-EDT2 for the identification of oligonucleotide sequences. We designed PNA sequences conjugated to either a tetracysteine motif and to split tetracysteine sequences, that are recognized by FlAsH. The effect of conjugation of the PNA to the tetracysteine peptide and RNA hybridization on the fluorescence of the arsenical complex has been investigated. The reconstitution of the tetracysteine motif, starting from 15-mer PNAs conjugated to split tetracysteine sequences and hybridized to a complementary oligonucleotide was also explored.bject]File in questo prodotto:
