COMPOSITION FOR REMOVING DNA- AND/OR RNA-CONTAINING BIOLOGICAL MATERIAL (VARIANTS) Russian patent published in 2023 - IPC A61L2/18 A61L101/26 A61L101/28 A61L101/22 A61L101/32 

FIELD: chemistry.

SUBSTANCE: group of inventions relates to liquid compositions made to remove DNA- and RNA-containing biological material from the surface of objects of inorganic and organic origin. Disclosed are compositions (variants) for removing DNA- and/or RNA-containing biological material, in the form of a mixture of the following two solutions: decontamination solution 1 (DCR-1) and decontamination solution 2 (DCR-2) at a ratio from 1:1 to 35:1, wherein DCR-1 may contain sodium dodecyl sulfate (SDS), copper (II) sulfate pentahydrate (CuSO₄×5H₂O), iron (II) sulfate heptahydrate (FeSO₄×7H₂O), tris (hydroxymethyl) aminomethane (Tris, (HOCH₂)₃CNH₂), glycerin, and deionised water; and DCR-2 contains hydrogen peroxide (H₂O₂), sodium benzoate (C₆H₅COONa), and deionised water.

EFFECT: removal of nucleic acids and destruction of cellular membranes on the surface of objects of inorganic and organic origin, including bone material, in laboratory conditions.
