Abstract
Determination of PCR products amplified by PCR can be readily and surely conducted even if multiple types of primers are used therein. By using a biochip of a glass slide with primers for the PCR implanted thereon, competitive PCR is performed in one tube with the multiple types of primers, and amplified PCR products are detected by use of the primers on the biochip.
Claims6
A method of detecting PCR-amplified base sequences, comprising the steps of:
- conducting PCR amplification by mixing a plurality of pairs of primers with a sample, said primers being suitable for amplifying different base sequences by PCR individually;
- conducting a hybridization reaction by using a substrate on which said primers used for the PCR are spotted and a solution containing said base sequences that are PCR-amplified in the preceding step, said hybridization reaction being performed between the primers spotted on the substrate and said PCR-amplified base sequences;
- and
- detecting spots on said substrate in which hybridization occurs.
1 more element
A detection kit for detecting PCR-amplified base sequences, comprising:
- a container containing a mixture of at least three types of primers, including:
- two types of primers suitable for amplifying a first base sequence specifically by PCR;
- and two types of primers suitable for amplifying a second base sequence different from said first base sequence specifically by the PCR;
- and
- a substrate on which a plurality of primers selected from said primers mixed in the container are spotted.
