Provided are synthetic strands for nucleic acid sequencing. In some embodiments, the strands include a plurality of rotatable molecular disks. The plurality of rotatable molecular disks comprises molecular disks each comprising a first moiety that binds to adenine (A), a second moiety that binds to cytosine (C), a third moiety that binds to guanine (G), and a fourth moiety that binds to thymine (T), uracil (U), or both (T/U). The first, second, third, and fourth moieties are spaced about the perimeter of the molecular disk. The molecular disks enable hybridization of the synthetic strand to a nucleic acid, where the rotational positions of the molecular disks indicate the sequence of the nucleic acid. Also provided are methods of using the synthetic strands, as well as related compositions, kits, and nucleic acid sequencing systems. Stem-loop structure-based sequencing methods and related compositions, kits, and nucleic acid sequencing systems are also provided.

Nucleic acid sequencing compositions and methods

The present disclosure provides compositions and methods for accurately detecting mutations by uniquely tagging double stranded nucleic acid molecules with dual cyphers such that sequence data obtained from a sense strand can be linked to sequence data obtained from an anti-sense strand when sequenced, for example, by massively parallel sequencing methods.

Compositions and methods for accurately identifying mutations

The present disclosure relates to compositions and methods for detecting rare nucleic acid molecule mutations in a plurality of nucleic acid molecules. Also disclosed are methods for determining the size of a nucleic acid molecule using droplet digital PCR.

Compositions and methods for detecting rare nucleic acid molecule mutations

Compositions and methods are described for highly sensitive quantification of the relative representation of DNA from adaptive immune cells (e.g., T and/or B lymphocytes) in DNA extracted from complex mixtures of cells that include cells which are not adaptive immune cells. Included are methods for determining the relative presence in a tumor of tumor infiltrating lymphocytes (TIL), the relative presence of lymphocytes infiltrating a somatic tissue that is the target of an autoimmune disease, and the relative presence of lymphocytes infiltrating a transplanted organ.
