  • Universal solid-phase hybridization apparatus
    Patent number: 6280945
    Abstract: A method of determining the presence of a nucleic acid analyte from a sample comprising binding a biotinylated capture oligonucleotide to a solid phase non-covalently coated with streptavidin or an avidin derivative. The capture oligonucleotide is contacted with and selectively hybridized to, under stringent hybridization conditions, a nucleic acid analyte to form a detectable hybridization complex.

  • Centrifuge tube phase separation plug
    Patent number: 5785925
    Abstract: A centrifuge sample tube phase separation plug is disclosed for use in conjunction with sample tube to effect organic solvent separation on a volumetric basis. The centrifuge sample tube is of the type having a conical bottom end closed at the apex with an upward extending cylindrical portion opening to the top of the sample tube. A centrifuge sample tube cap is provided to close the sample tube with the mixed organic solvent and sample. The sample tube cap contains a plug having a central aperture and a tapered profile for fitting into the top of the conical bottom section of the centrifuge sample tube. Presuming that the sample tube is loaded and capped with mixed organic solvent and sample, centrifugation occurs. Into the centrifugation process, the plug releases from the cap and passes from the cap area, through the sample, to the top of the conical portion of the centrifuge sample tube.
