Probe containing a modified nucleic acid, recognizable by specific antibodies and use of this probe and theses specific antibodies to detect and characterize a homologous DNA sequence

摘要

The invention relates to a kit for detecting the presence of a nucleic acid sequence, such as a gene or a gene fragment, in a composition or a specimen supposed to contain it. The kit comprises a probe containing a nucleic acid complementary with the nucleic acid sequence or gene which is sought. The probe bears at least one 7-iodo-N-2- acetylamino-fluorene group covalently fixed at one at least of the bases of this probe.
