| 摘要 |
A method for monitoring a reaction within a sample, said method comprising supplying or forming a double stranded polynucleotide having a fluorescence donor and a fluorescence acceptor molecule spaced along the length at a distance at which fluorescence from the donor is reduced by the acceptor, applying to said molecule a restriction enzyme which cuts said polynucleotide at a site intermediate said donor and said acceptor molecule, and monitoring fluorescence of said sample. The method is particularly suitable for detecting polynucleotide amplification, in particular in sequence detection but may also be used in enzyme quality control.
