  • Publication number: 20230314369
    Abstract: Provided herein is an electrophoresis separation medium comprising: (a) a non-crosslinked or sparsely cross-linked polymer or copolymer; (b) one or more denaturant compounds, in an amount sufficient to inhibit re-naturation of single stranded polynucleotides; (c) an aqueous solvent; (d) optionally, a wall-coating material suited to inhibition of electroosmotic flow; and (e) optionally, an organic water miscible solvent such as DMSO or acetonitrile, wherein the electrophoresis separation medium exhibits functional stability for at least seven days at 23° C. Also provided herein are sieving compositions, including polymer-based sieving compositions, for molecular sieving as well as related kits, devices and methods of use. Such compositions can be useful for separation of biomolecules such as nucleic acids, proteins, glycoproteins and glycans.

  • Patent number: 9834815
    Abstract: The present teachings generally relate to methods and kits incorporating a discriminating positive control for determining whether a particular microorganism or group of microorganisms are present in a sample, for example but not limited to a food, environmental, agricultural, biopharmaceutical, pharmaceutical, or water sample. According to certain methods, at least part of a starting material, for example but not limited to, a food, environmental, agricultural, biopharmaceutical, pharmaceutical, or water sample can be combined with a culture medium and incubated under conditions suitable for microbial growth followed by extracting microorganism and added control nucleic acids for analysis.
