Title: デジタルタンパク質短縮アッセイ法による疾患の検出
IPC: G01N33/574
Filed: 2002-12-04
Abstract: 原因遺伝子の変異を検出することによって遺伝病を診断することができる。短縮型変異の遺伝子産物を検出するためにタンパク質短縮アッセイ法を使用することができる。しかしながら、このアッセイ法の感度は、DNA試料中に低い頻度で存在する変異を検出するのに十分でないことが多い。変異対立遺伝子により生じるシグナルが試料分割前より全対立遺伝子の大きな割合を占めるように試料を分割することによって感度を高めることができる。従って、変異対立遺伝子により生じる以前は検出できなかったシグナルが、このアッセイ法において検出可能になる。このような高い感度によって、初期段階での、かつ他の対立遺伝子の濃度が高い試料における検出が可能になる。
