Figure 3. Viability of ARPE-19 Using the AlamarBlue Assay. Cell viability for ARPE-19 cells irradiated with UV radiation (0.0234, 0.702, and 1.404 J/cm2) as revealed by the alamarBlue assay; (a) cell groups without filter protections, (b) cell groups covered with 400 nm LP filters, and (c) cell groups covered with 320 nm LP filters. Significantly lower alamarBlue fluorescence for treated cells compared to control cells (p<0.05) is indicated by an asterisk (*).
