The present invention relates generally to the field of immune binding proteins and method for obtaining immune binding proteins from genomic or other sources. The present invention also relates to nucleic acids encoding the immune binding proteins in which the natural multimeric association of chains is maintained in the nucleic acids and the immune binding proteins made therefrom. For example, nucleic acids encoding antibodies that are amplified from a B-cell using the methods of the invention maintain the natural pairing of heavy and light chains from the B-cell. This maintenance of pairing (or multimerization) produces libraries and/or repertoires of immune binding proteins that are enriched for useful binding molecules.

Methods and systems are provided for massively parallel genetic analysis of single cells in emulsion droplets or reaction containers. Genetic loci of interest are targeted in a single cell using a set of probes, and a fusion complex is formed by molecular linkage and amplification techniques. Methods are provided for high-throughput, massively parallel analysis of the fusion complex in a single cell in a population of at least 10,000 cells. Also provided are methods for tracing genetic information back to a cell using barcode sequences.

A method and system for solid phase extraction of a compound of interest from a sample matrix using a syringe having a barrel and a plunger, a sorbent for use with the syringe, and a desalting purification column having an end configured to receive liquid from the syringe body.

Provided herein is a method for isolating high molecular weight (HMW) DNA using beads that are at least 200 μm in diameter that utilizes a device for retaining the beads and where the purified DNA eluant exits the device without shearing the HMW DNA. In some embodiments, the method comprises precipitating the DNA onto the beads, washing the beads in the device, and then eluting the DNA from the beads therein while substantially avoiding shear. Compositions and kits for practicing the method are also provided.

Described herein is method for purifying messenger RNA (mRNA) encoding a DNA endonuclease from a sample, the method comprising: (a) loading the sample comprising the mRNA onto a monolithic matrix comprising a poly(dT) or poly(U) nucleic acid molecule linked/coupled to the monolithic matrix under conditions allowing the mRNA to hybridize with the poly(dT) or poly(U) nucleic acid molecule; (b) eluting the mRNA from the monolith matrix after one or more contaminants have been separated from the bound mRNA; and (c) separating the mRNA from dsRNA by adsorption chromatography, thereby resulting in a purified mRNA solution.

A method for concentrating microorganisms, includes modifying an object by introducing an amine group into the object (step 1); and contacting a sample including a microorganism and dimethyl 3,3′-dithiobispropionimidate (DTBP) each other on the modified object (step 2), wherein the object is any one of a thin film device, a magnetic bead, a ring resonator, and a nanoparticle.

A device for extracting a nucleic acid from a sample liquid includes a heating element configured to be connected to an extraction nucleic acid. The extraction nucleic acid is at least partly complementary to the nucleic acid to be extracted from the sample liquid. The heating element is heatable to a temperature that is equal to or higher than a denaturing temperature of the nucleic acid bound to the extraction nucleic acid.

The present invention provides a method for improving the loading of nucleic acid on a solid support by contacting the solid support with a poloxamer-containing reagent. The present invention also provides a method for improving the stability of a nucleic acid on a solid support, comprising contacting a nucleic acid molecule with a partially double-strand oligonucleotide before or after loading the nucleic acid molecule on a solid support, so as to cause the nucleic acid molecule to hybridize with the oligonucleotide. The present invention also provides a combined use of the two methods.

A data storage medium is disclosed comprising a two-dimensional (2D) support structure onto which artificially synthesized DNA molecules encoding digital information are placed and then covered with a protective layer. The 2D support structure is formed from a material such as metal foil, glass, or plastic. The 2D support structure may be functionalized with positively charged molecules to improve DNA adhesion. The DNA is protected from degradation by encapsulation in a protective layer of a non-reactive material such as silica or a thin layer of metal. A process for storing DNA on 2D support structures is also disclosed. Correlation of specific DNA molecules with a physical storage location on a 2D support structure provides geometric addressability for selective access to specific digital information.

A microfluidic control system and method for separating flexible particles such as cell vesicles or biomacromolecules such as exosomes in a sample. The system of the present invention comprises one or more ultrahigh frequency acoustic resonators. The ultrahigh frequency acoustic resonators are capable of generating in a fluid channel an acoustic wave of which the frequency is about 0.5-50 GHz and propagated towards a wall opposite the fluid channel. By adjusting the power of the generated acoustic wave and/or the speed at which a conditioning solution flows through an acoustic wave area, flexible particles in a specified range are pushed to and remain at the top part of the flow channel in the acoustic wave area, while flexible particles outside of the specified range go downstream via the acoustic wave area to be collected, thus capturing or releasing the flexible particles in a solution such as cell vesicles or biomacromolecules, particularly exosomes.
