This LIVE/DEAD BacLight Bacterial Viability Kit provides two stains (separate and premeasured) in pairs of polyethylene transfer pipettes. The stains are supplied dry, without DMSO or other potentially harmful solvents, in the sealed pipettes. This stain formulation does not require refrigeration and is chemically stable even in poor conditions.

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