  • Publication number: 20140099674
    Abstract: This disclosure describes related novel methods for Recombinase-Polymerase Amplification (RPA) of a target DNA that exploit the properties of recombinase and related proteins, to invade double-stranded DNA with single stranded homologous DNA permitting sequence specific priming of DNA polymerase reactions. The disclosed methods have the advantage of not requiring thermocycling or thermophilic enzymes, thus offering easy and affordable implementation and portability relative to other amplification methods. Further disclosed are conditions to enable real-time monitoring of RPA reactions, methods to regulate RPA reactions using light and otherwise, methods to determine the nature of amplified species without a need for gel electrophoresis, methods to improve and optimize signal to noise ratios in RPA reactions, methods to optimize oligonucleotide primer function, methods to control carry-over contamination, and methods to employ sequence-specific third ‘specificity’ probes.

  • Publication number: 20130059290
    Abstract: A method includes contacting a crude matrix with components of an isothermal nucleic acid amplification reaction for a target nucleic acid species, thereby providing a mixture; incubating the mixture under conditions sufficient for the isothermal nucleic acid amplification reaction to proceed, thereby providing a product; and determining whether an indicator of the target nucleic acid species is present in the product.

  • Publication number: 20120129198
    Abstract: Assay systems and specialized antibodies for the detection and quantitation of troponin I and troponin T in body fluids as an indicator of myocardial infarction. Since troponin I and T exist in various conformations in the blood, the ratios of the monomeric troponin I an T and the binary and ternary complexes, as well as which form of troponin present in the blood, may be related to the metabolic state of the heart. Disclosed is a system to determine the presence of a troponin form or a group of troponin forms in a sample of whole blood, serum or plasma. Also disclosed are antibodies which recognize, unbound troponin forms, the forms of troponin in binary complexes, the ternary complex of troponin I, T and C, and the conformations of troponin I having intramolecularly oxidized and reduced cysteines.
