Design of dual-labeled oligonucleotide probes for SNPs genotyping.

Abstract

Our effort in designing base-discriminating fluorescence nucleosides (BDF), leads us to develop dual-labeled oligonucleotide probe in which the BDF nucleoside, (Py)U/(2-Ant)U act as the donor separated by a defined base pair distance from the acceptor, fluorescein, attached to 5'-end of the probe. Thus, a longer wavelength emission from acceptor might allow the probe to be used for SNP typing in chip based detection technology or in cell.
