There is provided a method for producing a peptide-nucleic acid complex containing a peptide and a nucleic acid encoding the peptide. The method for producing a peptide-nucleic acid complex includes a step of preparing a nucleic acid to which a transpeptidase N-terminal substrate motif has been added, the nucleic acid containing a first coding sequence encoding a peptide, a second coding sequence encoding a transpeptidase, and a third coding sequence encoding a transpeptidase recognition motif; a step of synthesizing a chimeric protein containing a domain of the peptide, a domain of the transpeptidase, and the transpeptidase recognition motif, from the nucleic acid to which the transpeptidase N-terminal substrate motif has been added, using a cell-free protein synthesis system; and a step of forming the peptide-nucleic acid complex by means of the transpeptidase domain.

An example method includes contacting a substrate coated with a sol-gel material with a stamp that includes a plurality of protruding features. While contacting the coated sol-gel material with the stamp, the example method further includes curing the coated sol-gel material so as to form a patterned sol-gel layer that includes a plurality of wells. The stamp is separated from the patterned sol-gel layer.

A method for the synthesis of a chimeric conjugate molecule by micellar catalysis that may form part of DNA-encoded compound libraries. A DNA-coupled organic starter molecule may be reacted with another organic compound, using a catalyst located within a micelle, to form a conjugate of an organic candidate compound coupled to a DNA identifier tag.

The present invention features a number of methods for identifying one or more compounds that bind to a biological target. The methods include synthesizing a library of compounds, wherein the compounds contain a functional moiety having one or more diversity positions. The functional moiety of the compounds is operatively linked to an initiator oligonucleotide that identifies the structure of the functional moiety.

Provided are compositions, methods and systems for determining the sequence of a template nucleic acid using a polymerase-based, sequencing-by-binding procedure. An examination step involves monitoring the interaction between a polymerase and template nucleic acid in the presence of one or more nucleotides. Identity of the next correct nucleotide in the sequence is determined without incorporation of any nucleotide into the structure of the primer by formation of a phosphodiester bond. An optional incorporation step can be used after the examination step to extend the primer by one or more nucleotides, thereby incrementing the template nucleotides that can be examined in a subsequent examination step. The sequencing-by-binding procedure does not require the use of labeled nucleotides or polymerases, but optionally can employ these reagents.

The invention provides for a panel for detecting chromosomal abnormalities in a plurality of cells in a cervical sample wherein the panel comprises a plurality of fluorescently labeled probes individually capable of hybridizing to specific chromosomal locations associated with a chromosomal abnormality in patients at risk for a cervical cell disorder. The invention also comprises a fluorescence in situ hybridization (FISH) probe set comprising the plurality of fluorescently labeled probes.

A nucleic acid patch method for amplifying target nucleic acid sequences in circulating free DNA or residual DNA samples where the defining ends of the target nucleic acid sequences are unknown.

The invention is a novel method of making and using a template for nucleic acid sequencing. The templates include circular and linear templates with symmetric and asymmetric adaptors. The methods include utilizing the templates in an asymmetric fashion.

Described herein are approaches allowing the storing of data at lower densities and increased write speeds. Indexing and recording of data may be separated into separate processes. Rapid DNA extension reactions can then be performed at many distinct locations throughout a solid support, so that the write speed is limited by the ability of the instrumentation to perform spatial addressing operations, rather than chemical synthesis steps.

Library preparation systems and methods are disclosed. An apparatus includes a plate receptacle, a magnet, a thermocycler, and an actuator. The plate receptacle is to receive a plate having a well and the thermocycler is to adjust a temperature of a sample within the well of the plate and the actuator is to move the magnet relative to the plate receptacle.
