CTC, 产品目录编号： # 19292
?5-氰基-2,3-二（4-甲基苯基）四唑氯化物（Cyanoditolyl tetrazolium chloride）可用于测定肿瘤细胞的氧化还原活性。
?其也可用于对食品样本、环境样本（尤其是水样）进行活细菌表位荧光显微计数。

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.
