Abstract: This disclosure provides an improved assay capable of identifying and distinguishing viral variants, such as SARS-CoV-2 variants and subvariants, including Alpha, Beta, Gamma, Delta, and Omicron, with high specificity and sensitivity. The disclosed assay can be used for real-time monitoring of viral variants (e.g., SARS-CoV-2 variants) spread without the need for whole-genome sequencing on all samples.

Abstract: An immobilized bimolecular construct comprises a solid support, a first oligonucleotide and a second oligonucleotide. The first oligonucleotide is labeled at one end with a fluorophore or quencher and attached at the other end to a solid support. The second oligonucleotide is labeled at one end with a fluorophore or quencher and hybridized at the other end to the first oligonucleotide. Hybridization of the second oligonucleotide with the first oligonucleotide brings the labeled end of the second oligonucleotide in close proximity or physical contact with the labeled end of the first oligonucleotide. In one embodiment the second oligonucleotide is also attached to the solid support in proximity to the first oligonucleotide. In this embodiment, the second oligonucleotide may be first attached to the solid support and then hybridized to the first oligonucleotide or, conversely, first hybridized to the first oligonucleotide and then attached to the solid support.

Abstract: A coding scheme for microcarriers suitable for use in distributed arrays includes labeling the carriers with quenched signaling hairpin molecules with any one of three to eight distinguishable fluorophores wherein the hairpins are of at least two types, most preferably three types, that open and fluoresce differentially as a chemical or physical condition, for example temperature, is changed. Mixtures of microcarriers having immobilized capture probes can be decoded by measuring fluorescence from said fluorophores under conditions under which only one type of hairpin is open, under which two types of hairpin are open, and so on. Mixtures of coded microcarriers with capture probes are used in assays for nucleic acids utilizing microarray methods.

Abstract: Hairpin-forming oligonucleotide probes and primers triple-labeled with a pair of florophores, a shorter wavelength harvester and a longer wavelength emitter, and a quencher. When the probes and primers are stimulated by light that excites the harvester, opening causes an increase in fluorescence by the emitter, while fluorescence from the harvester is continually suppressed. The probes and primers may be used for detection of nucleic acid targets in assays, including amplification assays. Assay kits are provided.
