以下の操作は,特に記載のないかぎり,室温(25℃)で行った。フィルタープレートを0.05%Tween−20/PBSで洗浄した。暗所でフィルタープレートの各ウェルにカルボキシビーズ(Luminex社製)を100μlずつ入れて吸引し,0.1M MES(2−モルホリノエタンスルホン酸)緩衝液(pH7.0)で洗浄し,50μlの0.1M MES緩衝液(pH7.0)を加えた。EDC(N−エチル−N’−(3−ジメチルアミノプロピル)−カルボジイミド塩酸塩)(10mg/ml/0.1M MES緩衝液(pH7.0))を各ウェルに10μlずつ添加した。
被験者から得た血清を10%ブロックエース(登録商標)/PBSで100倍に希釈した。フィルタープレートを0.05%Tween−20/PBSで洗浄し,先に作成したペプチド結合ビーズを5μl/ウェルで添加した。ビーズを0.05%Tween−20/PBSで洗浄した後,希釈血清を100μl/ウェルで加え,室温で2時間反応した。ビーズを0.05%Tween−20/PBSで洗浄し,ビオチン化ヤギ抗ヒトIgG(γ)抗体を100μl/ウェルで加え,室温で1時間反応した。ビーズを0.05%Tween−20/PBSで洗浄した後,ストレプトアビジン−R−フィコエリスリンコンジュゲート(SAPE)を100μl/ウェルで加え,室温で30分間反応した。次に,Luminex蛍光フローメトリーシステムで蛍光強度を測定した。
