Single cell cellular component enrichment from barcoded sequencing libraries
The present invention relates to the analysis of complex single cell sequencing libraries. Disclosed are methods for enrichment of library members based on the presence of cell-of origin barcodes to identify and concentrate DNA that is relevant to interesting cells or components that would be expensive or difficult to study otherwise. Also, disclosed are methods of capturing cDNA library molecules by use of CRISPR systems, hybridization or PCR. The present invention allows for identifying the properties of rare cells in single cell RNA-seq data and accurately profile them through clustering approaches. Further information on transcript abundances from subpopulations of single cells can be analyzed at a lower sequencing effort. The methods also allow for linking TCR alpha and beta chains at the single cell level.

Enhancing specificity of analyte binding
Methods for enhancing specificity of an analyte binding moiety or probe oligonucleotide to an analyte are provided herein. For example, methods provided herein include blocking a capture binding domain, thereby preventing hybridization to the capture domain of the capture probe affixed to a substrate. Further methods include releasing the block from the capture binding domain, thereby allowing the capture binding domain to specifically bind to the capture domain of the capture probe on the substrate.

NUCLEIC ACID AMPLIFICATION ASSAY USING 3-D MAGNETIC RESONANCE IMAGING DETECTION FOR SCREENING LARGE POPULATIONS
The present invention provides methods for high throughput screening and detection of nucleic acids from pathogens, such as SARS CoV-2, using nucleic acid amplification with nanoparticle binding complex formation and MRI or NMR detection. In certain embodiments, the MRI is three-dimensional MRI that simultaneously detects a plurality of amplified nucleic acid-nanoparticle complexes. In certain embodiments, the nucleic acids are amplified by isothermal LAMP techniques. In other embodiments, the nucleic acids are amplified by PCR. Methods of the invention are particularly useful rapid screening of large number of samples during pandemic situations.
