Abstract: Disclosed herein are novel methods and compositions for rapidly extracting and amplifying nucleic acids from a sample where the sample is combined with an extraction reagent comprising a reducing agent to form a mixture and incubating said mixture at ambient temperature for a period of time not exceeding 30 minutes to generate a nucleic acid extract. In certain embodiments of the method, the nucleic acid extract is subjected to a nucleic acid amplification reaction. In certain aspects, oligonucleotide primers specific for nucleic acids of Chlamydia species and/or Neisseria species are added prior to initiating the amplification reaction.

Abstract: Method of preparing a biological sample appropriate for use in a subsequent in vitro nucleic acid amplification reaction. A biological sample is combined with an alkaline composition that lyses cells and denatures DNA to create a first liquid composition. The first liquid composition is then mixed with a buffer, a detergent, and a solid support that captures DNA to create a second liquid composition. The buffer, detergent, and solid support can be delivered as components of a single reagent. Captured DNA strands can be used as templates in subsequently performed nucleic acid amplification and detection reactions with improved sensitivity.

Abstract: Provided herein are compositions and methods for the multiplexed profiling of RNA and DNA modifications across transcriptomes and genomes, respectively. The methods combine molecular recognition of non-canonical features (e.g., base modifications, backbone modifications, lesions, and/or structural elements) of a target nucleic acid with a step of writing the information from this recognition event into the neighboring genetic sequence of the target nucleic acid using a barcode. The resultant barcoded nucleic acids are then converted into sequencing libraries and read by DNA/RNA sequencing methods. This step reveals the sequence of the barcode, which is correlated with the non-canonical feature in the target nucleic acid(s). The high throughput profiling methods described herein allow for localization of one or more modifications in a target nucleic acid. The methods also allow for identification of the nature and location of several or all DNA/RNA modifications in parallel.

Abstract: Multivalent binding compositions including a particle-nucleotide conjugate having a plurality of copies of a nucleotide attached to the particle are described. The multivalent binding compositions allow one to localize detectable signals to active regions of biochemical interaction, e.g., sites of protein-protein interaction, protein-nucleic acid interaction, nucleic acid hybridization, or enzymatic reaction, and can be used to identify sites of base incorporation in elongating nucleic acid chains during polymerase reactions and to provide improved base discrimination for sequencing and array based applications.
