Description
本出願は、2001年6月20日に出願された米国特許仮出願第60/299,515号、2001年12月21日に出願された米国特許出願第10/028,852号、2001年12月21日に出願された米国特許出願第10/027,484号、2001年12月21日に出願された米国特許出願第10/027,516号、2001年12月21日に出願された米国特許出願第10/027,171号、2001年12月21日に出願された米国特許出願第10/027,922号、2001年12月21日に出願された米国特許出願第10/029,108号、および2002年1月24日に出願された米国特許出願第10/057,354号に対する優先権を主張するものである。これらの出願はすべて、参照として明示的に本明細書に組み入れられる。
本発明は、微細化システムにおいて試料を分離する装置および方法に関する。特に、本発明は、微細化毛管アレイ分離装置において流体を連通させる流体界面ポートに関する。
および遺伝子同定手順において、デオキシリボ核酸(DNA)、リボ核酸(RNA)、またはタンパク質が、その物理的性質および化学的性質に応じて分離される。DNA、RNA、またはタンパク質だけでなく、他の小さな分子アナライトも分離する必要がある。
本発明は、毛管または分離管路のアレイと液体を分離管路に導入し分離管路から除去する1つまたは複数の流体界面ポートとを含む、毛管アレイ電気泳動(CAE
)マイクロプレートなどの分離装置を提供する。例示的な態様の流体界面ポートは、分離装置を直接周囲の環境と連通させるポートであり、1つの分離管路の側壁に形成された開口によって形成される。この開口は、分離管路に液体分離媒体が満たされた場合に仮想壁を形成する。この開口は、毛管力によって分離媒体が分離管路内に保持されるように適切な断面寸法を有している。仮想壁は、開口部内の分離媒体のメニスカスによって形成され、試料管路を通る流体流に実質的に影響を与えないように基本的に分離管路の側壁の代わりとして働く。陰極リザーバは、1つまたは複数の分離管路と組み合わされている。いくつかまたはすべての分離管路に共通する陽極リザーバもマイクロプレート上に設けられており、各分離管路を通る電気経路を形成する。
本発明は、流体を導入し分離装置内の分離管路から流体を除去する改良された流体連通装置を提供する。本発明は、分離管路の側壁に仮想壁を形成する開口部を利用して流体試料を導入しかつ除去することによって、流体試料の制御性を改善し、注入効率を高め、スループットを向上させ、廃棄物を少なくする。本発明について、毛管アレイ電気泳動マイクロプレートを含む例示的な態様を参照して説明する。当業者には、本発明が電気泳動システムに限らず、電気クロマトグラフィーシステム、圧力駆動クロマトグラフィーシステム、および等電子集束システムを含むがそれらに限らない任意の適切な分離システムで実施できることが認識されると考えられる。
