Abstract:
This invention provides for a novel amplification procedure for nucleic acid. The method uses a wild type or mutant RNA polymerase designed to transcribe both deoxyribonucleotides and ribonucleotides (see figures 1-7).
Abstract:
Devices, processes, and kits for the extraction of nucleic acids from biological samples are disclosed. The devices comprise a first port, a second port, and a binding chamber intermediate and in fluid communication with the first port and the second port. The binding chamber comprises an unmodified flat glass surface effective for binding a heterogeneous population of nucleic acids. The first port, second port, and binding chamber define a continuous fluid pathway that is essentially free of nucleic acid-specific binding sites.
Abstract:
A process for isolating microorganisms is disclosed. The process utilizes a device comprising an inner surface, an outer surface, a first port, and a second port, wherein the inner surface comprises an unmodified, smooth glass substrate and defines a binding chamber providing fluid communication between the first port and second port. Microorganisms in an aqueous solution are contacted with the unmodified, smooth glass substrate, wherein the solution is essentially free of cell precipitants, and the microorganisms are allowed to bind to the glass substrate.
Abstract:
Processes for extracting nucleic acid from a biological sample and related assemblies and kits are disclosed. The processes comprise the steps of (a) providing a device comprising an inner surface, an outer surface, a first port, and a second port, wherein the inner surface is composed of unmodified, smooth glass and defines a tubular lumen providing fluid communication between the first port and second port, wherein the lumen is circular, oval, or elliptical in cross-section, and wherein the lumen is essentially free of nucleic acid-specific binding sites; (b) introducing a nucleic acid-containing sample into the lumen of the device via the first port; (c) allowing nucleic acid in the sample to bind to the unmodified smooth glass surface; and (d) washing the bound nucleic acid.
