Synthetic dyes are commonly used to assess the toxicity of chemical compounds in cell cultures. However, these dyes damage cells, rendering the cultures useless for long-term experiments. Recently, scientists discovered that a natural food pigment can replace synthetic dyes in cell viability assays for three widely varied types of cells -- and performs better. Their approach is also environment-friendly and inexpensive, and opens up possibilities in a range of fields including drug discovery.
