The present disclosure provides genetic constructs comprising a recombinant internal ribosome entry site (IRES), which may be used as riboswitches to modulate translation of an operably-mRNA sequence encoding a protein of interest. In other aspects, the disclosure provides recombinant cells, methods, kits and systems that utilize the same, e.g., to provide a platform for modulating the expression of essentially any protein of interest in a eukaryotic cell.

Methods of detecting and quantifying target molecules, such as proteins, in a biological sample are provided. The disclosed methods include capturing target molecules with aptamers, replacing the aptamers with aptamer identification sequences, and then sequencing the aptamer identification sequences using next-generation sequencing techniques.

A method for measuring an oligonucleotide which is simpler and more sensitive and has excellent specificity and quantitative capability compared to the conventional measurement method is provided. Moreover, a method for measuring an oligonucleotide having excellent specificity which can distinguish the intact target oligonucleotide (unchanged form) and a metabolite thereof and detect the unchanged form only is provided. In a hybridization method using a capture probe and an assist probe, by using a capture probe having a short nucleotide length in a certain range and the assist probe and causing hybridization under a specific positional relationship between the nucleotide-lacking-site in a metabolite of a nucleic acid drug and the capture probe, it becomes possible not only to detect the target oligonucleotide in a sample but also to distinguish from a metabolite of the nucleic acid drug.

Provided herein are methods and compositions for rapid, highly sensitive detection of molecular analytes such as antibodies, proteins, and small molecules using protein-driven nucleic acid assemblies to activate CRISPR-Cas nucleases. Also provided herein are uses of the sensitive analyte detection methods in an analyte detection platform and in convenient low-cost diagnostic assays such as lateral flow devices for point-of-care use.
