Expiry Date:	2022/07
Date of Production:	28/07/2020
HS265 is a reagent used to test for aldehydes and ketones and in histochemistry to detect polysaccharides, DNA and proteins. It consists of a solution of pararosaniline hydrochloride that has been decolourised by sulphur dioxide. Aliphatic aldehydes restore the pink immediately, whereas aromatic ketones have no effect on the reagent. Aromatic aldehydes and aliphatic ketones restore the colour slowly. HS265 may also be used in any other technique when Feulgen stain is specified.
