Marking reagents bearing diazo and nitro functions, methods for the synthesis of such reagents and methods for detecting biological molecules

摘要

The present invention relates to a labeling reagent of formula: in which: R1 represents at least one detectable label, L and A are each a linker arm, n is an integer equal to 1, and u is an integer between 0 and 2. The present invention also describes a method of synthesizing said markers and also applications for the labeling of biological molecules, more particularly nucleic acids, with a labeling reagent bearing diazo and nitro functions. The invention is particularly suitable for use in the diagnostics field.
