The invention concerns a method for labelling and fragmenting a single-stranded or double-stranded deoxyribonucleic acid (DNA) comprising the following steps: chemically fragmenting the DNA by generating an abasic site on said DNA, attaching a marker on at least one of the fragments by means of a labelling reagent, said reagent being covalently and majority bonded on at least one phosphate of said fragment. The invention is applicable in the field of diagnosis.
La présente invention concerne un procédé de marquage et de fragmentation d'un acide désoxyribonucléique (ADN) simple ou double brin comprenant les étapes suivantes : fragmenter chimiquement l'ADN en créant au moins un site abasique sur ledit ADN, attacher un marqueur sur au moins un des fragments par l'intermédiaire d'un réactif de marquage, ledit réactif se couplant de manière covalente et majoritaire sur au moins un phosphate dudit fragment. L'invention trouve une application préférentielle dans le domaine du diagnostic.
