USE OF COMPOSITIONS CONSISTING OF CATIONIC COMPOUNDS AND PROTON DONORS FOR STABILISING AND/OR ISOLATING NUCLEIC ACIDS IN OR FROM MICRO-ORGANISMS SUCH AS PROKARYOTS, FUNGI, PROTOZOA OR ALGAE

摘要

The present invention relates to the use of compositions for isolating and/or stabilising nucleic acids in or from microorganisms - such as prokaryotes, fungi, protozoa or algae. The composition contains, as an essential ingredient, a cationic compound of general formula T Ri wherein Y may denote nitrogen or phosphorus R1, R2, R3 and R4 independently of one another may denote an unbranched or branched C1-C20-alkyl group and/or a C6-C20-aryl group as well as a C6-C26-aralkyl group and X" may denote an anion of an inorganic or organic, mono- or polybasic acid .
