In Vitro	β-Amanitin (0.01-100 µg/mL; 36 hours) shows toxicity in MCF-7 cells, and the rates of cell viability are calculated as 52%, 62%, 84%, 86%, and 91% at concentrations of 100, 10, 1, 0.1, and 0.01 µg/mL, respectively[2]. β-Amanitin shows a great inhibition of protein synthesis at both concentrations (10 µg/mL and 1 µg/mL) in MCF-7 cells for 24 hours[2]. Cell Viability Assay[2] Cell Line: MCF-7 cells Concentration: 0.01, 0.1, 1, 10, 100 µg/mL Incubation Time: 36 hours Result: Showed toxicity in MCF-7 cells.
