    摘要: The present invention provides systems, methods, and compositions for nucleic acid detection based on non-mass determined base compositions. For example, in certain embodiments, base count data for a template nucleic acid is generated using an approach that does not measure molecular mass of the template nucleic acid (e.g., by sequencing the template nucleic acid) and a database comprising base count entries is queried to identify the target nucleic acid. In particular embodiments, sequencing is employed which is conducted in substantially real-time.

    摘要: Assays and methods including mobile tagged single stranded nucleic acid reagents pre-loaded on an analysis device, which are preferably tagged, but not labeled and are complementary to a strand (preferably the anti-sense strand in double stranded DNA targets) of the target nucleic acid. The assay also includes a running buffer that includes a dye or other detectable label that nonspecifically binds only to double stranded nucleic acids. In addition, the analysis device includes a detection zone including one or more test zones that have an immobilized tag that binds to the tag on the mobile nucleic acid reagent.

    摘要: In the present invention, an amplified DNA fragment having a first substance binding site to which a first substance is specifically bindable is prepared, which amplified DNA fragment amplified by a nucleic acid amplification method. The amplified DNA fragment is concentrated by binding the amplified DNA fragment to the first substance. The concentration makes it possible to detect the DNA highly sensitively. Therefore, with the arrangement, it is possible to detect the amplified DNA fragment amplified by the nucleic acid amplification method, easily and highly accurately without requiring any special device.

    摘要: A detection probe for detecting single base mutations or alterations in a double stranded target nucleic acid molecule is provided. In some aspects, the detection probe may include a double-stranded probe nucleic acid molecule having a first end and a second end; at least one probe initiation toehold at the first end; at least one substance capable of emitting a detectable signal at the second end; and optionally, at least one dissociation toehold at the second end. The detection probe is designed to hybridize with a double stranded target nucleic acid in a reaction which proceeds at approximate thermodynamic equilibrium (ΔG≈0) when no single base mutations or alterations are present in the double stranded target nucleic acid molecule. The probe may be used in detection systems and methods to identifying the presence or absence of one or more single base mutations or alterations in a double-stranded nucleic acid target molecule.

In some embodiments, a process comprises: amplifying a nucleic acid from a biological sample; ionizing and volatilizing the amplified product; analyzing the product by mass spectrometry to determine an observed molecular mass of the product; and comparing the observed molecular mass of the product to a calculated molecular mass of at least one nucleic acid having a known sequence, wherein the calculated molecular mass of the at least one nucleic acid having a known sequence is derived from the base composition of the at least one nucleic acid having a known sequence; whereby the presence or absence of the target nucleic acid is detected based on the comparison.

    摘要: Point-of-care binding assays include at least one target nucleic acid binding in a multiplex structure with at least one sequence in a partner nucleic acid associated with a label, due to complementary base pairings between at least one sequence in the target nucleic acid and at least one sequence in the partner nucleic acid. The assays overcome the inherent deficiencies of antibody-protein antigen assays. In a preferred embodiment, color tagged nucleic acid sequences are used to bind a complementary target nucleic acid. The tagged nucleic acid sequences are preferably made from deoxyribonucleotides, ribonucleotides, or peptide nucleotides.
