Provided herein are methods of determining a surgical margin and the site and size of a tissue to be resected from a subject, and methods of use thereof.

This disclosure demonstrates an approach that translates synthetic DNA codes to spatial codes registered in nanoliter microchambers for multiplexed measurement of nearly any type of molecular targets (e.g., miRNAs, mRNAs, intracellular and surface proteins) in single cells.

Methods and systems for decreasing amplification bias and primer-dimer formation in amplification reactions and for amplifying a plurality of target polynucleotides from a sample in a single reaction and for sequencing the target polynucleotides where samples can include forensic samples and where target polynucleotides can include identity- or ancestry-informative markers, short tandem repeats (STRs) and single nucleotide polymorphisms (SNPs). Methods of determining a nucleotide spacer sequence for disrupting primer dimer formation can include: receiving a set of primer sequences; determining a plurality of candidate spacers between an adapter sequence and a gene-specific portion of the primer sequence, the determined plurality of candidate spacers comprises sequences that disrupt stable interactions between sequences of the set of primer sequences; ranking candidate spacers that meet a predetermined threshold value of stable interactions in the extension sequences; and outputting a set of the ranked spacers that meet the predetermined threshold.

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.

This disclosure provides a powerful screening platform that combines pre-templated instant partitions with DNA-encoded library (DEL) technologies to identify target small molecule interactions and analyze their intracellular effects in single cell resolution using methods that require minimal sample preparation and affordable sequencing costs.
