Abstract
New sulfonated Cy3 and Cy5 phosphoramidites and solid supports were synthesized. These building blocks were used in the synthesis of terminally or internally labeled oligodeoxynucleotides. Mild deprotection schemes were applied to the sulfocyanine-labeled oligonucleotides.
Keywords: Oligonucleotides, fluorescent label, phosphoramidites, controlled pore glass, indocyanines, deprotection
