Abstract
Description
従来のポリヌクレオチド増幅装置は、少なくとも一つの0.2mlまたは0.5ml容積の反応管を使用し、同じ温度サイクルに露出させることによってポリヌクレオチドを増幅する。この場合、同じ温度サイクルで増幅するので、増幅される温度サイクルが異なる標的ポリヌクレオチドは、一つの反応では増幅できない。また、試料の量が最小0.2ml必要なので、サンプルを準備し難い。

重合反応チャンバに4Wの一定電力を加え、図1に示すような重合反応チャンバの周辺にグルーブが設置されたポリヌクレオチド増幅装置の温度上昇の様相を測定した。グルーブは、深さが全て250μmであり、グルーブの幅は各々100μm、1,000μm及び4、000μmである、3つの断熱グルーブを有するポリヌクレオチド増幅装置を使用した。対照群として、断熱グルーブのないポリヌクレオチド増幅装置を使用した。前記断熱グルーブのないポリヌクレオチド増幅装置は、断熱グルーブがないという点を除いては、図1に示す装置と同じである。
図3に示される4つのチャンバを含み、白金薄膜温度センサが設置されたポリヌクレオチド増幅装置を利用し、前記増幅装置内のチャンバ温度を制御した。
