  • Publication number: 20240279716
    Abstract: The present disclosure pertains to a method for detecting multiple target nucleic acids by a single type of label alone in a single reaction vessel by using multiple detection temperatures, which is characterized by providing a signal change dependent on the presence of a corresponding target nucleic acid at a corresponding detection temperature of each of the target nucleic acids. The conventional techniques using a single type of label is subjected to melting analysis after target amplification so as to detect multiple target nucleic acids. In contrast, the present method does not require melting curve analysis after target amplification, even using a single type of label, and thus can remarkably reduce the analysis time.

  • Publication number: 20240194300
    Abstract: The present invention relates to a method for calibrating a data set of a target analyte in a sample, wherein a normalization coefficient for calibrating the data set is provided by using a reflective value, a reference cycle and the data set, and the calibrated data set is obtained by applying the normalization coefficient to the signal values of the data set. The present method is very effective in removing the inter- and intra-instrument signal values of data sets. Furthermore, since the present method can be configured in software, the instant method is capable of being applied universally to various analytical instruments (e.g., a real-time PCR instruments) regardless of manufacture. Accordingly, the method by the present invention would be very useful in diagnostic data analysis.

  • Patent number: 10978173
    Abstract: The present invention relates to a method for reducing a noise level of a data set for a target analyte in a sample. The present invention can reduce a noise level of a data set to a proper level conveniently by applying a noise-reduction ratio to the data set thereby the possibility of false positive may be reduced effectively. According to the present invention, the calibrated data set is obtained by using the noise-reduction ratio, so that the noise level of a data set is reduced without change of signal ratio between the data point in the data set.
