廣泛應用于細胞生物學的各類實驗中,例如研究生長因子、細胞活素類和培養(yǎng)基組分,細胞毒性因子和淋巴細胞的活性。 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。 更多相關(guān)產(chǎn)品: BIOLOGICAL INDUSTRIES
