NUCLEIC ACID AMPLIFICATION METHOD AND NUCLEIC ACID AMPLIFICATION APPARATUS
A nucleic acid amplification method includes a step of heating a first region of a container housing a droplet containing a target nucleic acid and a sample necessary for amplification of the target nucleic acid to a denaturation temperature of the target nucleic acid and heating a second region different from the first region to a synthesis temperature of the target nucleic acid, and an amplification step of repeating a cycle through a denaturation stage at which the droplet housed in the container is moved to and retained in the first region and a synthesis stage at which the droplet is moved to and retained in the second region at a plurality of times. At the amplification step, periods of part of cycles of the plurality of cycles are made shorter than periods of the other cycles.

PCR APPARATUS COMPRISING REPEATED SLIDING MEANS AND PCR METHOD USING SAME
One embodiment of the present invention relates to a PCR apparatus comprising a repeated sliding means and a PCR method using same. According to the present invention, the throughput of samples can be increased by simultaneously, rapidly, and accurately performing a PCR on the large number of samples through repeated thermal contact between a PCR heating block having two or more heaters disposed therein and a PCR chip having two or more reaction chambers disposed therein. In addition, the present invention is capable of: significantly improving PCR yield by preventing radial heat distribution generated by the individual heaters and the consequent nonuniform thermal overlap between the adjacent heaters; significantly contributing to the miniaturization and integration of the apparatus by requiring no separate temperature control means; furthermore, simultaneously and rapidly amplifying multiple nucleic acid samples by using the PCR heating block having heater units repeatedly disposed therein and a plate-shaped PCR chip; and checking the process of nucleic acid amplification in real time by measuring sequential optical signals or electrochemical signals.
RECEPTACLE DISTRIBUTION SYSTEM
