  • Calcium binding proteolipid compositions and methods
    Patent number: 6444446
    Abstract: The invention relates to the cloning and sequencing of the DNA encoding a membrane associated proteolipid from C. matruchotii that is capable of inducing in vitro calcium binding. A proteolipid was extracted from cultures of C. matruchotii and separated into a lipid component and three apoproteins having molecular weights of approximately 5.0, 5.5 and 7.5 kDa as determined by SDS-PAGE. The invention also includes the polyclonal and monoclonal antibodies directed against the membrane associated proteolipid and immunological assays developed with these antibodies.
    Type: Grant

    Inventors: Barbara D. Boyan, Simon Van Dijk, David D. Dean
  • Horizontal flow generation system
    Patent number: 6079864
    Abstract: A fluid mixing system including a liquid mixing device and method for generating and maintaining a substantially uniform, horizontal velocity profile in a liquid circulation system, such as a plug flow reactor, which requires less horsepower than conventional liquid mixing systems without losing mixing effectiveness. The liquid mixing device employs a top-entry, vertically-oriented impeller and a housing that directs the pumped flow in a generally horizontal direction. The liquid mixing module may be positioned in close proximity to an aeration source within a channel.
