How to use

In Vitro:

Only the two highest concentrations of Erythrosine B tested (50.0 and 70.0 μg/mL) are significantly different (p<0.05) from the vehicle control group when the Tail Moment and Tail Intensity, which represent the extent of DNA damage, are analyzed. Results show increased micronuclei (MNi) frequencies at six of the seven Erythrosine B concentrations (0.2 to 70.0 μg/mL) when compare to vehicle control group.
