| 摘要 |
The present invention refers to a method that allows the use of filamentous bacteriophages to detect the presence of molecules of interest in biological samples. It consists of a series of combined operations, which are drawn up and defined according to the characteristics of the phages employed. These have, exposed on the surface of the capsid, at least one molecule, generally but not exclusively of proteic nature, capable of binding at least one molecule of interest present in said biological sample. Detection of the presence of said molecule takes place, according to the method of the invention, using the association between the molecule exposed on the surface of the phage and the genome of the phage itself. The ability to form specific complexes typical of the molecule exposed on the capsid, does enable formation of phage-molecule of interest complexes, which can be detected by means of amplification of known sequences in the phage DNA. The method according to the invention is extremely sensitive and can be used in particular for diagnostic and prognostic purposes.
