| 摘要 |
The invention concerns a kit for detecting and/or quantifying a ligant (C), present in an analysis sample, by a receptor (A), characterized in that it comprises the following reagents: a single-stranded or double-stranded nucleotide sequence (B), and said receptor (A) consisting of a monomeric or multimeric proteinic entity including at least a first recognition site specific for said ligand (C) and a second recognition site specific for said nucleotide sequence (B); said ligand (C) being capable of positively or negatively modulating fixing of the receptor (A) by its specific recognition site on the nucleotide sequence (B).
