Abstract: The present disclosure provides methods for isolating nucleic acids from a sample, comprising: (a) contacting a sample, a lysate of the sample, a supernatant of the lysate, or a portion of the sample, the lysate or the supernatant with one or more first agents (e.g., protein precipitating agents) and one or more second agents (e.g., inhibitor removing agents) to generate a mixture, (b) separating the mixture of step (a) into a solid phase and a liquid phase, wherein the one or more second agents are primarily in the solid phase, and (c) isolating nucleic acids from the liquid phase of step (b). Compositions and kits useful in such methods are also disclosed. Further disclosed are methods, compositions and kits for preparing a lysate using a lytic reagent comprising one or more relatively mild chaotropic agents and one or more phosphates from a sample, especially a complex sample, such as a soil or stool sample.

Abstract: The present invention generally relates to methods of generating antibodies against a species of pathogen that involve identifying the pathogen that is most genetically representative of member of pathogen species and using the identified pathogen to generate an antibody.

Abstract: The invention generally relates to using magnetic particles and magnets to isolate a target analyte from a body fluid sample. In certain embodiments, methods of the invention involve introducing magnetic particles including a target-specific binding moiety to a body fluid sample in order to create a mixture, incubating the mixture to allow the particles to bind to a target, applying a magnetic field to capture target/magnetic particle complexes on a surface, and washing with a wash solution that reduces particle aggregation, thereby isolating target/magnetic particle complexes.

Abstract: Provided herein is a new molecular marker in DNA: N-4-acetyldeoxycytidine (“N4-acdC”). Also provided herein are methods of detecting N4-acdC residues in DNA molecules as well as methods of using detected N4-acdC residues, for example in genetic mapping and diagnostics.

Abstract: Provided herein are methods for mapping modified nucleotide residues in nucleic acids. The methods include providing a nucleic acid sample in which non-target or target modified and unmodified nucleotide residues are converted to form of a different nucleotide (such a “C” being converted to “T”). Second strand synthesis is then performed on the converted nucleic acids using a set of anchored-base primers. Each primer in the set of anchored-base primers comprises one or more anchor bases at the 3? terminus that are complementary to the target nucleotide (e.g., “G” or “CpG”), and a sequence of nucleotides selected from a set of sequences that could be a fully or partially degenerate set of sequences. For example, the sequence could be 5?-XnG-3? and/or 5?-X(n?1)CG-3?, wherein X is any base, and n=2 to 25. Double-stranded nucleic acid products can be analyzed, for example by amplification and high throughput sequencing.

Abstract: The present disclosure provides methods for isolating proteins and optionally nucleic acids from a sample, comprising: (a) contacting a sample, a lysate of the sample, a supernatant of the lysate, or a portion of the sample, the lysate or the supernatant with one or more first agents selected from low molecular weight carboxylates and sulfate and one or more second agents that are multivalent (e.g., trivalent) salt(s) to generate a mixture, (b) separating the mixture of step (a) into a solid phase and a liquid phase, wherein the one or more second agents are primarily in the solid phase, and (c) isolating proteins and optionally nucleic acids from the liquid phase of step (b). Compositions and kits useful in such methods are also disclosed.

Abstract: The invention generally relates to a system for isolating or separating a target from a sample. In certain aspects, processes performed by the target capture system include introducing a plurality of magnetic particles, in which a plurality of the particles include at least one binding moiety specific to a target, into a sample to form at least one target/particle complex and applying a magnetic field to isolate the magnetic particle/target complexes from the sample. The process starts at inputting a sample into the system and ends at delivering a capture target or nucleic acids of the target into a container for further analysis.

Abstract: The invention generally relates to conducting an assay on a sample that isolates a pathogen from the sample and allows for analysis of the pathogen with minimal (i.e., at most 24 hrs of culturing) or no culturing of the pathogen. In certain embodiments, the invention provides methods for identifying a pathogen from a sample that involve obtaining a sample including a pathogen, conducting an assay that isolates the pathogen from the sample, culturing the isolated pathogen for at most about 24 hrs, and analyzing the pathogen.

Abstract: The invention generally relates to methods of using compositions that include sets of magnetic particles, members of each set being conjugated to an antibody specific for a pathogen, and magnets to isolate a pathogen from a body fluid sample.
