Abstract (en)

[origin: WO2005092910A1] The invention relates to a temperature-stable labelling reagent having formula (0), wherein: R<1> represents H or an alkyl, aryl or substituted aryl group; R<2> represents a detectable label or at least two detectable labels which are inter-linked by at least one multimeric structure; L is a linker arm comprising a linear chain 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, -CO-NH-(CH2)3-(O-CH2-CH2)3-CH2-NH-R<2>, -CO-NH-(CH2)3-(O-CH2-CH2)4-CH2-NH-R<2>, in which R = alkyl or aryl; A is a linker arm comprising at least one double covalent bond enabling the conjugation of the diazo function with the aromatic ring and u is an integer of between 0 and 2, preferably 0 or 1; -Y-X- represents -CONH-, -NHCO-, -CH2O-, -CH2S-; -Z- represents -NH-, -NHCO-, -CONH- or -O-; m is an integer of between 1 and 10, preferably between 1 and 3; and p is an integer of between 1 and 10, preferably between 1 and 3. The invention also relates to a method for the synthesis of said labels and to the use thereof for labelling biological molecules, particularly nucleic acids, with a labelling reagent bearing the diazomethyl function. The invention is particularly suitable for use in the field of diagnostics.
