| 摘要 |
The present invention is directed to a platform technology for quick and easy detection and identification of single or multiple microorganisms in a sample using peptide labeled oligonucleotides (PLONs). The PLONs are specifically designed to be complementary to certain nucleic acid sequences on a target microorganism. When the PLONs of the present invention are added to nucleic acids extracted from a sample (both biological and/or non-biological), they hybridize to the specific target nucleic acids of the microorganisms, and the PLONs are then detected with one or more specific enzymes coupled to antibodies that are specific to the conjugated peptides attached to the PLONs. The hybridized PLON-enzyme coupled antibody complex is further localized to a test region on a solid matrix or support by the presence of a composition comprising a secondary antibody to enzyme coupled antibody and provides a specific, sensitive, easy to use tool for the detection and identification that does not require any amplification step and any equipment for the final read out. A kit and methods of use of the invention are also provided.
