MycoLight 比率菌膜電位試劑盒是美國AAT Bioquest生產(chǎn)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(xiàn)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(fā)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(fā)波長為常見的激發(fā)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。
