  • Analyte detection in particulate-containing samples
    Patent number: 5494800
    Abstract: A method of determining the presence and quantity of an analyte of interest in a particulate-containing sample is disclosed, as is a construct for use in the method. The method is particularly useful for determining an analyte in whole blood and in fermentation suspensions. The construct is comprised of a first moiety, which is a particulate-binding moiety and a second moiety, which binds the analyte of interest.
    Type: Grant
    Filed: April 29, 1994
    Date of Patent: February 27, 1996
    Assignee: CytoSignet, Inc.

  • Method for binding biologically active compounds
    Patent number: 4007089
    Abstract: A method for binding biologically active compounds to carriers comprising reacting an asymmetric bifunctional linking compound having at least one phenyl azide moiety and at least one s-triazine moiety with a carrier in the presence of light to form a carrier bound to the linking compound through the phenyl azide moiety, and reacting said carrier bound to the linking compound with a biologically active compound under reaction conditions sufficient to bind the biologically active compound to the linking compound through the s-triazine moiety.
