Publication number: 20230279479Abstract: The present disclosure is directed to methods and processes that may be used to increase the signal of a target-specific reporter molecule (such as a probe) by covalently attaching plural copies of a fluorophore to a target-reporter duplex that are excited by iFRET (induced fluorescence resonance energy transfer) from donor fluorescence of a double-stranded DNA-binding dye bound to the double-stranded DNA structure created by hybridization of reporter and target during an amplification reaction. In one illustrative example, a double-stranded DNA-binding dye is provided in solution and during amplification and/or after completion of amplification, the dye binds to the probe-target duplex, and provides fluorescence resonance energy transfer to multiple acceptor fluorophores that are covalently attached to the duplex.Type: ApplicationFiled: December 23, 2022Publication date: September 7, 2023Applicant: Co-Diagnostics, Inc.Inventors: Luming ZHOU, Carl T.
