Overview
About Acriflavine Neutral
Acriflavine Neutral is a mixture of 3,6-diamino-10-methylacridinium chloride and 3,6-diaminoacridine, supplied without the extra hydrochloric acid carried by Acriflavine Hydrochloride. A 5% solution in water is clear, with a pH of about 4.5 to 7.5.
Like the hydrochloride, it binds nucleic acids and fluoresces strongly, so it is chosen where a method calls for acriflavine but a less acidic solution is needed.

Questions
Frequently asked
How is it different from Acriflavine Hydrochloride?
It contains the same acridine dyes without the extra hydrochloric acid, so its solution is close to neutral (pH 4.5 to 7.5). Choose it when your method needs a less acidic solution.
