Abstract
Description
しかし、多くの状況において、より高いスループットが必要となるので、センサ表面上にはさらに多くの検出スポットが求められる。
1. ポート38iからポート38aへ、例えば緩衝液などの保護流体を流しながら、ポート36iからポート36aに活性化流体を流すことによる第1のセクション58aの活性化(図13a)
2. フローチャネル34a〜iに沿ってリガンド溶液を流すこと、それによりリガンドは各チャネルとSPR検出線9bに沿って検出スポットを形成する第1のセクション58aの交差領域で固定化される(図13b)
3. ポート38iからポート38aへ、例えば緩衝液などの保護流体を流しながら、ポート36iからポート36aに非活性化流体を流すことによる第1のセクション58aの非活性化(図13c)
4. 適宜、第2のセクション58bに段階aからcを繰り返し、相応してSPR検出線9aに沿った検出スポットを形成する前記セクションの交差領域でリガンドを固定化すること(図13a〜c)。或いは、第2のセクション58bの検出スポットは基準スポットとして空白にしておく。
5. SPR検出線9a及び9bに沿った検出スポット13の相互作用レスポンスを記録しながら、フローチャネル34a〜iに沿ってアナライト溶液を流すこと(図13d)
6. ポート36i及び38iからポート36a及び38aに再生成流体を流すことによってすべての検出スポット13において同時に固定化されたリガンドを再生成すること(図13e)
図14a及び図14bは、交差するフロー経路の境界面位置60が、例えば1以上の追加の交差する検出線9cを流体力学的に処理するために、2つの流体の相対流量を制御することによって変位される一実施形態を示す。そのような境界面の流体力学的な位置決めを達成するさまざまな方法は、例えば、参照によって全体をここに援用する、米国特許第7811515号、米国特許第7219528号、米国特許第7015043号、及び国際公開第2003102580号に開示されている。
