Abstract:
Methods for preparing and utilizing tunable electrostatic capture ("TEC") ligands that have an ionizable function are provided. The electrostatic nature of the ionizable functionality of the TEC ligands can be "tuned" or adjusted to either reversibly bind or release a desired target anion, such as a biomolecule, by varying the pH and/or the ionic strength of the binding conditions and release conditions. The TEC ligands can be bound to a solid support to form TEC binding surfaces. TEC surfaces, ligands, solid supports and the accompanying methods and buffer systems can be used to isolate polyanions, such as nucleic acids, from materials, for example in a size-selective manner.
Abstract:
Provided are methods of phase-defined genotyping of both alleles of the glycosyltransferase (ABO) locus of a human subject. In certain embodiments the methods include a sequencing step using next-generation sequencing. In certain embodiments the methods include a sequencing step using sequencing-by-synthesis. In certain embodiments the methods further include the steps of comparing contiguous composite nucleotide sequences to a library of reference genomic sequences encoding a region comprising exon (6) and exon (7) of the ABO locus, and identifying individual contiguous composite nucleotide sequences as either (i) a sequence encoding a region comprising a known exon (6) and exon (7) of the ABO locus, or (ii) a sequence encoding a region comprising a novel exon (6) and/or exon (7) of the ABO locus. Also provided are kits for phase-defined genotyping of both alleles of the ABO locus of a human subject.
Abstract:
Arrays of integrated optical devices and their methods for production are provided. The devices include an integrated bandpass filter layer that comprises at least two multi-cavity filter elements with different central bandpass wavelengths. The device arrays are useful in the analysis of highly multiplexed optical reactions in large numbers at high densities, including biochemical reactions, such as nucleic acid sequencing reactions. The devices provide for the efficient and reliable coupling of optical excitation energy from an optical source to the optical reactions. Optical signals emitted from the reactions can thus be measured with high sensitivity and discrimination. The device arrays are well suited for miniaturization and high throughput.
Abstract:
A sequencing instrument optical system having a combined light source with multiple collinear excitation beams having different respective excitation wavelengths, a sequencing surface having DNA templates and nucleobase labels configured to emit a respective emission light at a different respective emission wavelength upon excitation by one or more of the excitation beams, a color camera configured to detect the emission light of each of the nucleobase labels, a first optical pathway configured to direct the collinear excitation beams from the combined light source to the sequencing surface, and a second optical pathway configured to direct the emission light from the sequencing surface to the color camera.
Abstract:
Composite liquid cell supports are provided. Aspects of the supports include: a plurality of CLC containers, wherein each CLC container is configured to hold a CLC and comprises a fluorophilic inner surface having a water contact angle of 80 degrees or greater. The fluorophilic inner surface may have a first contact angle with a fluorous carrier liquid which is less than a second contact angle with an encapsulating liquid that is immiscible with the carrier liquid. The supports find use in, among other applications, CLC systems and devices. Also provided are methods of preparing and using CLC arrays that include the CLC supports of the invention.
Abstract:
Self-sustained, safe, stable and scalable microbial consortia (S5MicroCon) are described. The microbial consortia are regulated by photoautotroph-heterotroph interactions and RNA aptamer-based gene circuits. A rapid, high-throughput method for engineering RNA aptamer-based gene circuits (e.g. riboswitches) is also described.
Abstract:
A condition can be diagnosed based on a symptom experienced by a subject and based on a biological sample including nucleic acids. Based on the symptom, a first set of the nucleic acids can be preselected for analysis. A first plurality of the nucleic acids of the first set that are present in the first biological sample can be captured. For each of the captured nucleic acids of the first plurality, an amount of that captured nucleic acid that is present in the first biological sample can be quantified and sequenced and based on the sequence of that captured nucleic acid, an origin of that captured nucleic acid can be identified. An indication can be output of the quantified amount and the identified origin of at least one captured nucleic acid that is present in the first biological sample.
Abstract:
Methods, apparatuses, and systems for screening, analyzing and selecting microorganisms from complex heterogeneous communities, predicting and identifying functional relationships and interactions thereof, and synthesizing microbial ensembles based thereon are disclosed. Methods for identifying and determining the absolute cell count of microorganism types and strains, along with identifying the network relationships between active microorganisms and environmental parameters, are also disclosed.
Abstract:
In some embodiments, the disclosure relates generally to methods, as well as related systems, compositions, kits, apparatuses and computer-readable media, comprising a multiplex molecular tagging procedure that employs a plurality of tags that are appended to a plurality of polynucleotides. The tags have characteristics, including a sequence, length and/or detectable moiety, or any other characteristic, that uniquely identifies the polynucleotide molecule to which it is appended, and permits tracking individual tagged molecules in a mixture of tagged molecules. For example, the tag having a unique tag sequence, can uniquely identify an individual polynucleotide to which it is appended, and distinguish the individual polynucleotide from other tagged polynucleotides in a mixture. In some embodiments, the multiplex molecular tagging procedure can be used for generating error-corrected sequencing data and for detecting a target polynucleotide which is present at low abundance in a nucleic acid sample.
