Abstract

While the colorimetric assay commonly referred to as ‘MTT’ does provide an indication of effects of photodamage on mitochondrial enzyme levels, a careful analysis showed that the resulting data were not correlated with a clonogenic assay. While MTT data can be claimed to represent ‘cytotoxicity’, this is an undefined term and appears not to be necessarily correlated with the object of anti-tumor therapy: tumor eradication. Use of this assay for assessing effects of treatment on viability are therefore unreliable.

MTT分析的陷阱和其他问题。

虽然通常被称为“MTT”的比色法确实提供了光损伤对线粒体酶水平影响的指示，但仔细分析表明，所得数据与克隆测定无关。虽然MTT数据可以声称代表“细胞毒性”，但这是一个未定义的术语，似乎与抗肿瘤治疗的目标：肿瘤根除并不一定相关。因此，用这种方法来评估治疗对生存能力的影响是不可靠的。
