生存率用のイメージングアッセイでは、集団分析と同じ原理が用いられます。細胞膜が損なわれた細胞では、DNAに結合した場合のみ蛍光を発する細胞透過性DNA結合試薬が細胞内へ流入します。したがって、集団内の個々の細胞用の生存率指標としてDNA染色を用いることができます。
フローサイトメトリー用の細胞生存率アッセイもご覧ください。
細胞膜完全性は、細胞生存率アッセイにおいて通常測定されるパラメーターです。一方、膜が損なわれた細胞では、細胞不透過性DNA結合色素が入り、これによるDNA染色が生存率指標 として用いられます。 マルチパラメーターアッセイは、生細胞および死細胞の両方を検出して総計を得ることができます。これらのアッセイは、生存率に対する系としてエステラーゼ活性またはミトコンドリア機能の測定を提供し、生細胞および死細胞の両方の状態を決定するより多くの情報を提供します。 染色試薬の選択が可能なキットは、ハイコンテントスクリーニングに最適化されており、蛍光抗体ベースの検出によるさらなるマルチプレックス化を可能にします。 | LIVE/DEAD® Cell Imaging Kitを用いて染色されたHep G2細胞。 |
損傷細胞および死細胞の細胞膜では透過性が高まり、 試薬の細胞内への流入が可能になります。コンビネーションアッセイは複数のパラメーターを測定して、生細胞および死細胞の両方の状態を決定するためのより多くの情報を提供します。
