'Multiplex quantitative PCR based on novel design of fluorescent primers is described. Fluorogenic primers are labeled with a single fluorophore on a base close to the 3'' end with no quencher required. A tail of 5-7 nt is added to the 5'' end of the primer to form a blunt-end ... More
Effect of primary and secondary structure of oligodeoxyribonucleotides on the fluorescent properties of conjugated dyes.
We studied fluorescence intensity, polarization and lifetime of some commonly used fluorophores conjugated to oligodeoxyribonucleotides with different primary and secondary structures. We found that fluorescence intensity can increase or decrease upon hybridization of the labeled strand to its complement depending on the sequence and position of the fluorophore. Up to ... More
