  • Method for determining the presence or concentration of a bound enzyme
    Patent number: 5354655
    Abstract: There is disclosed a process and a device for detecting and measuring (1) the amount of enzyme present as a detecting system following a nucleic acid hybridization reaction or immunoreaction; (2) the level and activity of free enzyme in a biological sample; (3) the level of enzyme from contaminating microorganisms present in a sample; and (4) enzymes from pure culture isolates for microbial identification and antimicrobial susceptibility testing.
    Type: Grant
    Filed: March 29, 1988
    Date of Patent: October 11, 1994
    Assignee: BioControl Systems, Inc.
    Inventors: N. Robert Ward, Jr., Philip J. Lozier

  • Process and device for sequential microbial enrichment in a single apparatus
    Patent number: 5188946
    Abstract: There is disclosed an apparatus, a device, and a method using the inventive device and apparatus for the sequential enrichment of a particular microorganism to a threshold level to allow for its detection. The use of the apparatus for sequential microbial enrichment shortens the time period normally spent to enrich samples to permit the growth of enough microorganisms to detect the particular microorganism(s) of interest. The invention eliminates the need for multiple manual transfers of potentially biohazardous materials.
    Type: Grant
