  • Publication number: 20040023271
    Abstract: The present invention provides novel methods of indirect analyte dectection and quantification through amplification of oligonucleotide template attached to binding partners for analytes by nucleic acid amplification utilizing isothermal, single primer linear nucleic acid amplification methods. Methods for binding of binding partner that is attached to an oligonucleotide template to analyte, then amplifying at least a portion of the oligonucleotide template using a composite primer, primer extension, strand displacement, and optionally a termination sequence, are provided. Methods for amplifying sense RNA using a composite primer, primer extension, strand displacement, optionally template switching, a propromoter oligonucleotide and transcription are also provided. Methods for detecting and quantifying amplification products are also provided. The invention further provides compositions and kits for practicing said methods.

  • Patent number: 4981786
    Abstract: A device is disclosed for conducting an assay. The device comprises a housing, means enclosed in the housing for capturing a first member of a specific binding pair (sbp) in a zone and for allowing liquid to be transported by capillary action away from the zone, first means in the housing for introducing the sample into the device, and second means in the housing other than the first means for introducing a liquid reagent other than the sample into the device. The device of the invention finds use in assay methods for the determination of an analyte in a sample suspected of containing the analyte. Kits for conducting an assay are also disclosed.
