Fluorescence Polarization Based Nucleic Acid Testing for Rapid and Cost-Effective Diagnosis of Infectious Disease.


ABSTRACT: A new nucleic acid detection method was developed for a rapid and cost-effective diagnosis of infectious disease. This approach relies on the three unique elements: 1)?detection probes that regulate DNA polymerase activity in response to the complementary target DNA; 2)?universal reporters conjugated with a single fluorophore; and 3)?fluorescence polarization (FP) detection. As a proof-of-concept, the assay was used to detect and sub-type Salmonella bacteria with sensitivities down to a single bacterium in less than three hours.
