Description

DAB buffer is a reagent specifically designed for optimal signal intensity and contrast. When in the presence of peroxidase enzyme and DAB solution, the buffer helps create a brown precipitate that is insoluble in alcohol.

When in the presence of peroxidase enzyme and DAB solution, the buffer helps create a brown precipitate that is insoluble in alcohol. The standard working dilution is 50ul (0.9mg) of DAB solution per 1ml of DAB buffer, although the ratio can be adjusted as desired, the use of liquid components reduces some risks associated with handling powders, and eliminates waste which often results from using tablets that require a predetermined final volume. Once the two components are combined, the reagent can be used for up to six hours, making it ideal for automated stainers.
