Abstract: A method for quantitative assessment of base excision repair (BER) and nucleotide excision repair (NER) DNA repair capacities of at least one cellular extract, which method entails: a) preparing a range of plasmids with at least one physical or chemical treatment or both and recovering a supercoiled fraction of each of said plasmids, b) characterizing the lesions present on each of the plasmids of the range of plasmids; c) depositing the plasmids of the range of plasmids, and at least one supercoiled control plasmid without lesions onto a single solid support, according to a pre-established configuration A, so as to form a functionalized support divided into different zones A1 to Ax, corresponding to an integer equal to the number of cellular extracts to be simultaneously tested, each zone containing supercoiled plasmids treated with at least one physical or chemical treatment that induces a lesion acted upon by BER mechanisms, and at least one other zone containing supercoiled plasmids treated with at least

Abstract: The invention concerns nucleic acid detection using a probe consisting of: a binding domain A, consisting of a single strand polynucleotide; and intermediate domain B, consisting of at least a stop synthon; and a display domain C, consisting of a double strand polynucleotide, wherein is incorporated at least a marked nucleotide constituting detection means. The use of said probes amplifies the hybridisation signal with nucleic acid target sequences.

Abstract: A method for detecting specific nucleic acid sequences (a single sequence and/or a mixture of nucleic acid sequences) which are present in a biological sample, comprising at least one enzymatic amplification. Detection is carried out, after placing the biological samples in a solution in order to extract the nucleic acid, by enrichment with target sequences by putting the biological samples into contact with at least one pair of appropriate triggers, followed by at least one appropriate dilution of the obtained enrichment amplifying solution, and by putting a fraction of this solution into contact with at least one pair of triggers, followed by the detection of the obtained double-strand target nucleic acid copies. Applications in the diagnosis of genetic, infectious and tumoral diseases, in checking biological samples and in cell typing etc.
