  • Patent number: 10801058
    Abstract: Disclosed is a method of quality control of nucleic acid amplification using quality control oligonucleotide. The method comprises a nucleic acid detection step and a determination step. The nucleic acid detection step comprises the steps of: preparing a nucleic acid sample containing a target nucleic acid and a quality control polynucleotide; preparing a compartment containing one molecule of the target nucleic acid and a compartment containing one molecule of the quality control polynucleotide; and carrying out nucleic acid amplification of the target nucleic acid and the quality control polynucleotide, in the compartments, and carrying out signal detection using a detection probe to detect a signal originated from the detection probe. In the determination step, it is determined as to whether or not the nucleic acid detection step is proper on the basis of the result obtained in the signal detection step.
