1. A method for labeling nucleic acids, the method comprising:
- introducing the nucleic acids and labels or labeling precursors into a reaction chamber, the labels or labeling precursors comprising a diazo function and the reaction chamber having immobilized capture molecules capable of binding the labels or labeling precursors at least partially on an inner surface of, or on a solid support in, the reaction chamber;
reacting the nucleic acids with the labels or labeling precursors to label or pre-label, respectively, the nucleic acids by reacting the diazo function with phosphate groups of the nucleic acids; and
covalently bonding unreacted labels or labeling precursors to the capture molecules.

Abstract
The present invention relates to a method for labeling biological molecules of interest contained in a biological sample, consisting in:
- a) providing a reaction vessel,
- b) immobilizing capture molecules, which are capable of binding a label of the biological molecules of interest, on a solid support of the vessel,
- c) introducing the biological sample but also at least one label of the biological molecules of interest into said vessel and optionally any ingredient required for labeling or prelabeling the molecules of interest,
- d) incubating the vessel content and immobilizing the label which is not reacted with the molecules of interest by binding to the capture molecules, and
- e) using the labeled molecules of interest for subsequent steps.
A method for treating a biological sample is also disclosed.
Said invention is preferably used in a manual or automated method for purifying nucleic acids.
