  • Immunogens, derivatives and immunoassay for ethyl glucuronide
    Publication number: 20060240496
    Abstract: Ethyl glucuronide (“EtG”) analogs can be prepared for use as immunodiagnostic reagents and in immunodiagnostic protocols. The EtG analogs can be in the form of EtG-based immunogens, and EtG-based antigens. The EtG-based immunogens can be used for preparing anti-EtG antibodies, which can be used in immunoassays. Accordingly, improved immunoassay techniques for detecting EtG can be performed with the EtG-based antigens, and anti-EtG antibodies prepared from EtG-based immunogens.

  • Chromogenic substrate to detect urine adulteration
    Patent number: 6503726
    Abstract: A device and method to detect oxidant adulterants added to a sample to prevent detection of tetrahydrocannabinol and/or tetrahydrocannabinol metabolites. The device and method detect popularly available adulterants such as chromate and nitrite through their reaction with a chromogenic substrate for a peroxidase enzyme. The substrate may be applied to a pad. A change in color in the presence of the oxidant may be detected directly or indirectly. The device and method may be used to detect the presence of any oxidant adulterant and is not specific for only one or a few adulterants added to a urine sample submitted for drug testing.
    Type: Grant
    Filed: February 27, 2001
    Date of Patent: January 7, 2003
    Assignee: Applied Biotech, Inc.
