該步驟僅提供指南，應根據(jù)您的特定需求進行修改。在制備ROS Brite?工作溶液之前，根據(jù)需要處理細胞。
1）在DMSO中制備10至20mM ROS Brite TM APF（或HPF）儲備溶液。通過將DMSO儲備溶液稀釋到含有20mM Hepes緩沖液（HHBS）的Hanks溶液中，制備1至10μM的工作溶液。
2）根據(jù)需要處理細胞（例如，用50-100nM血管緊張素II處理RASM細胞3-5小時）
3）用ROS Brite?APF（或HPF）（1-10μM，步驟＃1）在37℃孵育細胞20-60分鐘。
4）用HHBS緩沖液替換染料加載溶液。
5）用適當?shù)臒晒鈨x器在Ex / Em = 490 / 525mm（截止= 515nM）下用底部讀取模式分析細胞（例如，用于熒光顯微鏡的FITC濾光器，用于流式細胞儀的FL1濾光器）。
注意：BSA和酚紅會影響熒光，應謹慎使用。 APF和HPF均可用于溶液測定或細胞內(nèi)測量。
