プライマリー細胞ベースのADCCアッセイの不確実性とバラつきを解消
Fc受容体を介した抗体依存性細胞傷害(ADCC:Antibody-dependent cell-mediated cytotoxicity)は、抗体が罹患細胞を標的として排除するための重要な作用機序(MOA)です。ヒトFcγRIIIa遺伝子は158番目のアミノ酸残基をコードする位置に多型を示します。これにより、158番目のアミノ酸がバリン(V)である高親和性FcγRIIIaバリアント(V158)と、フェニルアラニン(F)を持つ低親和性バリアント(F158)が生じます。
従来のADCC測定には、細胞表面にFc受容体を発現するドナー由来の末梢血単核球(PBMC)または精製ナチュラルキラー(NK)細胞が使用されてきました。標的細胞の傷害がこの経路活性化のエンドポイントとなりますが、これらのプライマリー細胞ベースのアッセイはアッセイ間のバラつきが大きく、調製が煩雑で、バックグラウンドが高くなることが課題でした。
ADCC Reporter Bioassayはプライマリー細胞培養を不要にすることで、従来法の多くの課題を克服しています。

- ハイスループットワークフローにも容易に対応
アッセイ原理
このFc Effector Reporter Bioassayは、従来のプライマリー細胞ベースのアッセイとは異なる検出法を採用しています。エフェクター細胞内でFcγRおよびNFATを介したルシフェラーゼ活性の活性化を検出します。プライマリー細胞は、ヒトFcγRIIIa V158およびNFAT誘導性ルシフェラーゼを安定に発現するJurkat細胞株に置き換えられています。
発光アッセイによる Fc エフェクター活性のモニタリング
標的細胞に結合した抗体のFc領域がADCC Bioassay Effector Cellsに認識されると、FcγRIIIaを介した細胞内シグナルが伝達され、NFAT誘導性ルシフェラーゼ活性として容易に定量できます。
アッセイパフォーマンスデータ
正確度(Accuracy)と精度(Precision)は、バイオアッセイおよびバイオロジクス開発において非常に重要です。ADCC Reporter Bioassayはこの両方を兼ね備えています。
- 正確度:参照値または「標的」値をどれだけ忠実に再現できるかの指標
- 再現性:同一条件下(同一分析者・同一ラボ・同日)で同一均質サンプルを複数回アッセイした際の再現性の指標
- 中間精度:異なる分析者・機器・日時で同一均質サンプルを複数回アッセイした際の再現性の指標
- 直線性:サンプル濃度に比例した測定値が得られるかどうかの指標
