Aim. To study the binding of a water-soluble cationic Pheophorbide-a derivative (CatPheo-a) ta a Na+–stabilized antiparallel quadruplex formed by 22-mer oligonucleotide d[AG3(T2AG3)3] of the human DNA telomeric sequence (Tel22, PDB ID: 143D). Methods. Absorption and polarized fluorescence spectrosco...
