CTC, 產(chǎn)品目錄編號(hào)： # 19292
•5-氰基-2,3-二（4-甲基苯基）四唑氯化物（Cyanoditolyl tetrazolium chloride）可用于測(cè)定腫瘤細(xì)胞的氧化還原活性。
•其也可用于對(duì)食品樣本、環(huán)境樣本（尤其是水樣）進(jìn)行活細(xì)菌表位熒光顯微計(jì)數(shù)。
•運(yùn)用該方法就可定量檢測(cè)海水中的細(xì)菌。
•該方法可在2至10分鐘內(nèi)檢測(cè)到80%的活細(xì)菌。
•當(dāng)將細(xì)胞樣本與CTC混合儲(chǔ)藏于冰箱中或液氮中時(shí)，可至少保存四星期而不導(dǎo)致大量細(xì)胞死亡。

產(chǎn)品具體信息
Cyanoditolyl tetrazolium chloride has been used to measure the redox activity of tumor cells. It has also been employed for direct epifluorescent microscopic enumeration of respiring bacteria in food samples and environmental samples, especially water samples. Reveals a quantitative methodology for measuring marine bacteria. These methods yield 80% activity in 2 to 10 minutes. Cell samples mixed with CTC can be stored refrigerated or frozen in liquid nitrogen for at least 4 weeks without a significant loss of cells.
