  • Preparation of a red blood cell component for a hematology control
    Patent number: 7482161
    Abstract: Red blood cells from a vertebrate are treated to make them effective components of a hematology control, allowing the control to be used for detecting all blood cell components, including white blood cells and platelets. The treatment includes the use of a fixative under limited conditions of concentration and exposure time, and the resulting red blood cells are stable but lysable in a hematology instrument and have a reduced tendency to form particulates.

  • Composition for manipulating optical and electrical properties of particles to achieve target values for such properties and methods for using the composition
    Patent number: 6146901
    Abstract: A composition and a method for using the composition for manipulating the electronic and optical properties of biological particles are disclosed. The composition generally has a hypotonic buffering solution, a polyhydroxy alcohol, a stabilizing agent, and, in some applications, a non-ionic surfactant. By varying the relative concentrations of these components and by adjusting the timing of their combination and interaction, the composition and method allow for the alteration of the electronic and optical properties of the particles to achieve target values for the properties. In one particularly advantageous application, the composition and method of the invention allow for the creation of selected analogs for the subpopulations of human leukocytes from a single biological particle for use as a control product in differentiating particle analyzers.
