Abstract
A two-step method of labelling DNA through aliphatic amino groups with various reporter molecules has been developed. The method is based on reaction of cytosine-residues of polynucleotide chain with 4-aminooxybutylamine; the latter's synthesis is described. DNA modified on this way with fluorescein isothiocyanate functions a probe in molecular hybridisation. The sensitivity of this method for fluorochrome-labelled DNA probes in the dot hybridisation procedure is about 200 pg per mm2.
