摘要:
The field of the present invention pertains to a controlled transfer biological collection device using a dry solid storage and transfer medium and a method for the collection of biological material of interest (genetic or proteinaceous material) in a form suitable for storage and/or subsequent analysis. Specifically, the present invention provides for a sampling device that controls the transfer of the biological sample to the storage medium by holding the storage medium and a moveable sample collection member having an analyte collection surface. The invention further provides for a method not only for storing a biological analyte on this collection device but also for analyzing the stored biological analyte using methods that are suited for automated analyzing systems.

摘要:
The present invention provides methods and kits for detection, and optionally quantitation, of multiple nucleic acid sequence analytes in a single fluid sample. The assays and kits of the invention employ a plurality of species of capture probes, each species comprising a bacteriophage covalently or non-covalently linked to an oligonucleotide complementary to one analyte, wherein the bacteriophage of each species is capable of generating a distinctive signal when plated on an indicator medium. The oligonucleotide moieties of each capture probe contain a sufficient number of contiguous ribonucleotides to confer sensitivity to a ribonuclease specific for RNA/DNA or RNA/RNA duplexes. In the method of the invention, the capture probe species are combined with the fluid sample, which has been processed to release single-stranded nucleic acids. Hybridization is allowed to occur, thereby generating DNA/RNA or RNA/RNA duplexes. By adding a nucleolytic enzyme capable of cleaving DNA-RNA duplexes, bacteriophage are released for detection of the different signals on an indicator medium. The kit of the invention provides components which allow the method of the invention to be performed.
