The WST-1 assay is an efficient test for cell viability measurement and the standard incubation time is 2h. In order to test if one-time addition of WST-1 reagent can reflect the relative cell viability trend of the testing agents at different time points, the effects of 2h standard incubation time and long term incubation time (2h+24h, 2h+48h) of WST-1 were compared in the rat airway smooth muscle cells (ASM cells) after adding of the testing protein MRP-14. Our study demonstrated that the effect of different dosages of the protein after 2h WST-1 incubation on ASM cells showed a tendency of inhibition and achieved the maximal inhibition effect at 72h. The relative cell viability trend of the 2h+24h group was the same to that of the 2h WST-1 incubation, which means that 24h prolonged incubation time of WST-1 reagent could still reflect the relative cell viability trend. In conclusion, the study suggested that the WST-1 is a proper candidate reagent for continuous monitation of cell viability.
