After removing the culture medium, fresh media containing variousc

6、oncentrations of NPPB is added, and incubated for 24 h. Next, 100 L of Thiazolyl blue tetrazolium bromideat 0.5 mg/mL is added to each well and incubated at 37C for 1 h. Cells are then dissolved in 100 L ofDMSO, and the absorbance is measured at 570 nm with a Microplate Reader. Concentration-respons
