Abstract
【課題】マイクロチップ自体の蛍光強度がバックグラウンドとして作用しても、高精度かつ短時間に蛍光標識された生体試料の蛍光強度を検出する蛍光検出方法を図る。 【解決手段】蛍光標識された生体試料(R)が供給されたマイクロチップ(10)と同等のマイクロチップ(11)自体から発生する蛍光(Lk0)の蛍光強度(Ur0)を励起光(Le)の照射開始から蛍光強度(Ur0)が十分に減衰するまで検出し、蛍光強度(Ur0)の経時変化を記憶する。マイクロチップ(10)に励起光(Le)を照射すると共に、マイクロチップ(10)自体からの蛍光強度(Ur0)が十分に減衰する前に、生体試料(R)を供給し、発生する蛍光強度(Ur)を励起光(Le)の照射開始から生体試料(R)が供給された後まで検出する。生体試料(R)が供給されたマイクロチップ(10)から検出された蛍光強度(Ur)から、記憶された蛍光強度(Ur0)の経時変化の値を減算して、生体試料(R)から発生した蛍光(Lk)の蛍光強度(Uc)を検出する。
