摘要:The invention concerns a temperature-stable labelling reagent of formula (I), wherein: R<1> represents H or an alkyl, aryl or substituted aryl group; R<2> represents a detectable marker or at least two detectable markers linked together by at least a multimeric structure; L is a linking arm comprising a linear catemer concatenation of at least two covalent bonds; and n is an integer equal to 0 or 1; R<3> and R<4> represent, independently of each other: H, NO2, Cl, Br, F, I, R<2>-(L)n-Y-X-, OR, SR, NR2, R, NHCOR, CONHR, COOR with R = alkyl or aryl, A is a linking arm comprising at least a double bond enabling the conjugation of the diazo function with the aromatic cycle; and u is a whole number between 0 and 2, preferably between 0 and 1; and -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-. The invention also concerns a method for the synthesis of said markers and uses for labelling biological molecules, in particular nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly applicable in the field of diagnosis.
