Provided herein are high-throughput sequencing methods to study the diversity and functionality of lymphocyte receptor chains and pairing of the same. Specifically, the methods provided herein are used to identify with confidence one or more lymphocyte receptor chain pairs in a sample, for example one or more functional chain pairs.

Disclosed is an in situ method for detecting spatial proximity relationships between nucleic acid sequences, such as DNA, in a cell. The method includes: providing a sample of one or more cells comprising nucleic acids; fragmenting the nucleic acids present in the cells that leaves 5′ overhanging ends; filling in the overhanging ends with at least one labeled nucleotide; joining the filled in end of the fragmented nucleic acids that are in close physical proximity to create one or more end joined nucleic acid fragments having a junction; isolating the one or more end joined nucleic acid fragments using the labeled nucleotide; and determining the sequence at the junction of the one or more end joined nucleic acid fragments.

Novel methods that may be used for the manufacture of plant alkaloid compounds and novel polynucleotide compounds are provided. The plant alkaloid compounds are useful as medicinal compounds.

A method to detect chromatin-interacting RNAs in any given state of a cell or tissue by examining global RNA interactions with DNA by deep sequencing. A method to generate a global view of chromatin-RNA interactome by mapping the binding locations on the genome of each detected chromatin interacting RNA.

The present disclosure is directed to methods and kits for identifying, enriching, and evaluating templated assembly reactants. Some embodiments disclose methods for identifying templated assembly targets by synthesizing templated assembly reactants, hybridizing the templated assembly reactants to target nucleic acids, performing a templated assembly reaction, and identifying the target nucleic acids that hybridized to the templated assembly reactants. Libraries of templated assembly reactants, a kit for identifying templated assembly targets, and a pair of templated assembly targets enriched from a library of chemically-ligated oligonucleotides spatially elicited (CLOSE) products are also disclosed.

Provided herein are methods for selecting polypeptides or proteins having one or more desired properties from a library of sequences expressed in eukaryotic cells, comprising: encapsulating said cells by photopolymerization; solubilizing said encapsulated cells to produce semipermeable microcapsules; optionally contacting said cells and/or said microcapsules with one or more agents to facilitate detection of activity or function of polypeptides or proteins of interest; and selecting polypeptides or proteins of interest having one or more desired properties. Also provided are methods for encapsulating eukaryotic cells for use in the selection of polypeptides and proteins as described above.

Micron scale biogeography is a major driver of physiology and ecology of complex microbial biofilm communities, which remains elusive largely due to the lack of tools for spatially resolved phylogenetic mapping. This disclosure provides methods, computer-readable storage devices and kits that allow highly multiplexed and spatially resolved imaging of microbial community spatial organization. The disclosure provides a highly-multiplexed approach to resolve the spatial structure of complex microbial community at high taxonomic resolution.
