  • Method for fragmenting and labeling DNA involving abasic sites and phosphate labeling
    Patent number: 7060441
    Abstract: A single- or double-stranded deoxyribonucleic acid (DNA) is fragmented and labeled by chemically fragmenting the DNA by creating at least one abasic site on the DNA, and attaching a marker to at least one of the fragments by means of a labeling reagent, the reagent covalently and predominantly coupling to at least one phosphate of the fragment. This method can be applied in the field of diagnosis.

  • Process for labeling a nucleic acid
    Patent number: 6902891
    Abstract: A process of fragmenting and labeling a synthetic or natural nucleic acid, comprising the steps of providing a mixture containing a nucleic acid, a labeling agent containing a detectable label, and at least one multivalent metal cation in a substantially aqueous solution; chemically fragmenting the nucleic acid in the mixture to produce a multiplicity of nucleic acid fragments; and attaching at least one label to at least one of the nucleic acid fragments to produce a detectably labeled nucleic acid fragment.
