Figure 1. The effect of azacytidine (AZC) treatment on retinoblastoma Y79 cell survival for 5 days was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT assay).The bar diagram shows that 80% percent of Y79 cells were viable on 5th day of AZC treatment at 5 µM concentration. Error bar represents the standard deviation of triplicate values.
