The LIVE/DEAD BacLight Bacterial Viability Kit *for microscopy and quantitative assays* is a convenient and easy-to-use kit for monitoring the viability of bacterial populations as a function of the membrane integrity of the cell. Cells with a compromised membrane that are considered to be dead or dying will stain red, whereas cells with an intact membrane will stain green.

Any physiological buffer between pH 7.0–8.0, including PBS, can be used to dilute the SYTO dyes for the staining solution.
