MTT和XTT都是檢測細胞存活和生長的方法，MTT的產(chǎn)物為水不溶性的藍紫色結(jié)晶甲瓚（Formazan），并沉積在細胞中，需要加有機溶劑溶解，由于在去上清的操作時會有可能帶走小部分的甲瓚，故重復性略差。XTT作為線粒體脫氫酶的作用底物，被活細胞還原成水溶性的橙黃色甲臢產(chǎn)物，當XTT與電子偶合劑（例如PMS）聯(lián)合應用時，其所產(chǎn)生的水溶性的甲臢產(chǎn)物的吸光度與活細胞的數(shù)量成正比。

XTT優(yōu)點：

1. 使用方便，省去了洗滌細胞

2. 檢測快速
3. 靈敏度高，甚至可以測定較低細胞密度

4. 重復性優(yōu)于MTT

適用于單核細胞（Monocytes）,人肝癌細胞Hep G2胚胎纖細胞 Ehd-1, 小鼠纖維細胞，惡性黑色素瘤A375，胰腺癌BXPC-3等30余種細胞類型。
