    • 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 surfaces 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 the biological sample. Detection of the presence of the molecule takes place, according to the method of the invention, using the association between the molecule exposed on the surfaces of the phage and the genome of the phage itself. The ability to form specific complexes typical of the molecule exposed on the capsid enables 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.
    • 本发明涉及允许使用丝状噬菌体来检测生物样品中感兴趣的分子的存在的方法。 它由一系列联合作业组成,根据所采用的噬菌体的特点制定和定义。 这些具有暴露在衣壳表面上的至少一种能够结合存在于生物样品中的至少一个目标分子的分子,通常但不仅限于蛋白质性质。 使用暴露在噬菌体表面上的分子与噬菌体本身的基因组之间的关联,根据本发明的方法发生分子存在的检测。 形成在衣壳上暴露的分子典型的特异性复合物的能力能够形成感兴趣的噬菌体分子复合物,其可以通过噬菌体DNA中已知序列的扩增来检测。 根据本发明的方法是非常敏感的,并且可以特别用于诊断和预后目的。
