[list_product_images]Figure 1. Absorption spectrum of WST-8 formazan|Figure 2. shows the absorption spectrum of WST-8 formazan. Since the absorbance at 460 nm is proportional to the number of viable cells in the medium, the viable cell number can be determined using the absorbance of a previously prepared calibration curve.|Figure 3.
