Scientists know several methods to distinguish living cells from dead ones in toxicological
Now scientists have discovered an alternative to DET withsynthetic dyes: dye exclusion method using natural pigment made from Monascus purpureus (MP). This is a type of mold traditionally used in Asia for the production of fermented foods.
In a recent study, the teamresearchers have proven that MP can be used to determine the viability of breast cancer cells. The scientists found that, unlike trypan blue, MP does not damage living cells and is resistant to the typical chemotherapy drug cisplatin. What's more, it took only ten minutes to stain dead MP cells, and its cost is ten times less than trypan blue.
