Resazurin Assay: Resazurin sodium salt was purchased from Acros Organic. For cell viability experiments exploring propachlor treatments, 50,000 cells were plated in 64 wells in a Poly-D-Lysine coated 96 well plate. Each row was treated with an increasing amount of propachlor for 30 minutes starting with 0 mM to 1 mM propachlor in serum free media. The media was then changed and allowed to recover for 24 hours. Two mg of resazurin sodium salt was resuspended in 1 ml of DPBS. 5 µl of resazurin solution was added to each well. The final concentration for each well was thus 380 µM.
