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.
