MycoLight 比率菌膜電位試劑盒是美國AAT Bioquest生產的用于檢測菌的試劑盒，AAT Bioquest的MycoLight 比率菌膜電位試劑盒使用熒光傳感器，在低濃度的革蘭氏陽性和陰性菌細胞中均呈現綠色熒光，但由于較大的染料分子聚集，熒光在較高的細胞溶質濃度下向紅色發射轉移膜電位。 膜電位的大小隨著不同的菌種類而變化。 對于許多革蘭氏陽性物種，紅/綠比率傾向于隨質子梯度的強度而變化，而在許多革蘭氏陰性菌中，染料的響應似乎與質子梯度強度不成比例。 該試劑盒設計用于在菌濃度范圍為每毫升105-107個生物體時測定菌膜電位。 可以在510-530nm（FITC濾波片組）和600-660nm（德克薩斯紅色濾波片組）下熒光測量染色細胞，激發波長為常見的激發光源488nm。百螢生物是AAT Bioquest的中國代理商，為您提供的MycoLight 比率菌膜電位試劑盒。
