Method and system for dna detection

A DNA detection system comprising:

• an imaging device that captures an image of a device capable of arranging a DNA solution in each of a plurality of partitions, wherein the DNA solution may contain a plurality of types of DNAs including a first gene and a pseudogene of the first gene, and the DNA solution contains a fluorescent-labeled probe or a DNA intercalator;
• a temperature adjustment unit that changes a temperature of each of the partitions in order to perform PCR in each of the partitions;
• a database that stores information indicating a reference melting temperature for each of the first gene and the pseudogene;
• an imaging control unit that causes the imaging device to capture an image in order to acquire a fluorescence intensity changing with a temperature change for each of the partitions;
• a melting temperature memory that stores information indicating a melting temperature of a double strand DNA placed in the partition, for each of the partitions, wherein the melting temperature is obtained based on a change in the fluorescence intensity accompanying a temperature change in an image captured by the imaging device;
• and
• an analysis unit that counts the number of partitions in which the first gene is placed and the number of partitions in which the pseudogene is placed using the database and the melting temperature memory, wherein the analysis unit outputs the number of partitions counted for each type of the DNA and discriminates the first gene and the pseudogene based on the meting temperature and the number of counted partition, wherein the analysis unit determines whether a ratio of the number of partitions in which the pseudogene is placed to the number of partitions in which the first gene is paced is a value within a range corresponding to 1, a value within a range corresponding to ½, a value within a range corresponding to 2, a value within a range corresponding to 0, or a value not within any range, and determination is made whether or not the ratio conforms to a predetermined value or range, and if the ratio conforms to the predetermined value or range, information indicating conformity is displayed, and if the ratio does not conform to the predetermined value or range, information indicating non-conformity is displayed.
