  • Kit containing glutaraldehyde coated colloidal metal particles of a preselected size
    Patent number: 5571726
    Abstract: A method and test kit useful in a wide variety of immunoassay systems. A method of producing metal sol reagents containing metal sol particles of a preselected size is provided. A metal containing solution is reduced under optimized pH conditions to produce metal sol particles of a preselected size, the particles are coated with a coupling compound and then bound with at least one selected immunochemically reactive component. Particles having different immunochemical specificities are also mixed to produce reagents having multiple selected immunochemical specificities.
    Type: Grant
    Filed: May 19, 1995
    Date of Patent: November 5, 1996
    Assignee: Ortho Diagnostic Systems, Inc.
    Inventors: Houston G. Brooks, Jr., Chi-Deu Chang, Utpal R. Chakraborty, Henry A. Graham, Jr., Lloyd L. Hollenbeck, Jr., Sharon R. Lawler, Jennifer Nasser, Ernest G. Schutt, Albert Venturini
