Monitoring hybridization during PCR

摘要

A method for detecting a target nucleic acid sequence in a biological sample during amplification comprising adding a thermostable polymerase and primers configured for amplification of the target nucleic acid to the biological sample, amplifying the target nucleic acid sequence by PCR in the presence of a heat labile double-strand specific dye, conducting the PCR through a number of amplification cycles, illuminating the biological sample comprising the amplified target nucleic acid sequence with light at a wavelength absorbed by the dye, and detecting a fluorescent emission from the dye related to the quantity of the amplified target nucleic acid sequence in the sample.
