METHOD FOR LABELLING AND FRAGMENTING DNA

摘要

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.
