Barcoded solid supports and methods of making and using same

Aspects of the present disclosure include methods of making barcoded solid supports. In some embodiments, the methods include producing a concatemer by rolling circle amplification (RCA) of a circular nucleic acid template, where the circular nucleic acid template includes a barcode and a stem-loop forming region, and where the concatemer includes a plurality of linked units, each unit including the barcode and a stem-loop structure formed from the stem-loop forming region. Such methods further include disposing the concatemer on a solid support to produce a barcoded solid support including a plurality of the stem-loop structures extending from the surface of the solid support. The methods may further include treating the stem-loop structures with an agent that produces stem structures having ends compatible with target nucleic acids, and attaching the target nucleic acids to the stem structures. Barcoded solid supports and methods of using the barcoded solid supports are also provided.

Transcription Mediated Amplification Methods for RNA Detection

Provided herein is a method for detecting the presence of a COVID-19 virus RNA or other pathogenic respiratory viruses, such as an influenza virus, or other RNA of interest in a sample. Nucleic acids are obtained from the sample and are used as a template in a combined isothermal reverse transcription, RNAse H and isothermal amplification reaction to generate single stranded RNA amplicons containing sequences complementary to fluorescent labeled detector probes. The single-stranded RNA amplicons hybridize to the detector probe and to hybridization probes with sequences complementary to a sequence determinant in the COVID-19 or other virus RNAs. The microarray is imaged to detect fluorescent signals thereby identifying the virus.
