| Product: | Feulgen Stain (Schiff) | | Code: | HS265 | | Lot: | 170751 | | Issue Date: | 30/08/2017 | | Expiry Date: | 2019/07 | | Date of Production: | 12/07/2017 | | 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. | | This product has been checked against the current TCS specification for the following test(s): | | | | Result | | Stain intensity | SOP 6A.0 | Conforms | | Stain colour | SOP 6A.0 | Conforms | | Background | SOP 6A.0 | Conforms | | Absence of precipitate | SOP 6A.0 | Conforms | | Uniform staining | SOP 6A.0 | Conforms | | Visual QC check | SOP Manual 6 | Conforms |
