Fluorescent-based techniques for viral detection, quantification, and characterization.
Fluorescent-based technologies offer opportunities for developing new assays for detection, quantification, and characterization of viral isolates. According to the intrinsic characteristics of fluorescent-based tools (high specificity, sensitivity, and reliability), such type of molecular assays makes possible investigations on original studies such as evolutionary processes (including fitness measurement of isolates), quantitative epidemiology, or the analysis of synergism and antagonism between closely related isolates. The development of these tools is very simple and requires, in complement to basic molecular knowledge such as extraction, cloning, and (RT)-PCR procedures, only the identification of short specific sequence(s) in the targeted viral genome. The Single Nucleotide Polymorphism (SNP) and the 'real-time' RT-PCR assays are proposed as fluorescent-based tools for qualitative and quantitative viral detection, respectively. Moreover, the SNaPshot technology is described as method for isolate characterization.
