    摘要: The present disclosure describes a method and apparatus for collecting samples of particles from air or other gases at one or more monitored locations, and identifying in real-time whether biological agents, such as bacterial or viral pathogens, are present in the samples. The apparatus preferably uses a liquid-assisted collector to collect the sample of particles, which are suspended in a liquid that contains dyes that detect the presence of nucleic acids. An integrated detector with a light source and a light detector detects whether there is a change in the fluorescence of the liquid, which indicates the presence of a biological agent in the sample.

    摘要: A method of generating a double stranded (ds) recombinant nucleic acid molecule covalently linked in both strands by contacting two or more ds nucleotide sequences with a topoisomerase under conditions such that both termini of at least one end of a first ds nucleotide sequence are covalently linked by the topoisomerase to both termini of at least one end of a second ds nucleotide sequence is provided. Also provided is a method for generating a ds recombinant nucleic acid molecule covalently linked in one strand, by contacting two or more ds nucleotide sequences with a type IA topoisomerase under conditions such that one strand, but not both strands, of one or both ends of a first ds nucleotide sequence are covalently linked by the topoisomerase. Compositions for performing such methods, and compositions generated from such methods also are provided, as are kits containing components useful for conveniently practicing the methods.
