Particle counting nucleic acid hybridization assays |
April 14, 1992 |
| An improved nucleic acid hybridization assay, relying on particle counting, is provided. Presence and quantity of target nucleic acid is determined by detecting, upon hybridization, signals associated with particle aggregation or coincident signals from particles and reporters. |

Electrochemical determination of hematocrit |
October 13, 1987 |
| A method for measuring hematocrit is provided. An electrochemically detectable marker is measured before and after the ratio of red cell volume to plasma volume is decreased. The measured concentrations are used in a mathematical formula to determine hematocrit value. |

Differential pressure capillary viscometer for measuring viscosity independent of flow rate and |
December 9, 1986 |
| A means for measuring either the intrinsic or inherent viscosity of a solute in solution with a solvent which is independent of flow rate and temperature fluctuations. The solution is passed through one capillary tube and the solvent through a second capillary, and the pressure drop |

Particle reagent size distribution measurements for immunoassay |
June 4, 1985 |
| A highly sensitive and rapid method for quantitatively assaying analytes in liquid media by directly measuring changes in particle size distribution of reagent particles having analyte insolubilized thereon in a system undergoing antibody-induced aggregation has been developed. The amoun |
