  • Method for making unclipped HIV envelope protein
    Patent number: 5849533
    Abstract: Methods for making unclipped HIV env proteins are provided. According to the methods, a genetically engineered cell line comprising an nucleic acid sequence encoding an HIV env protein is cultured to produce unclipped HIV env protein, which is recovered from the cell culture.
    Type: Grant
    Filed: February 19, 1997
    Date of Patent: December 15, 1998
    Assignee: Genetech, Inc.

  • Molecularly cloned diagnostic product and method of use
    Patent number: 4855224
    Abstract: A molecularly cloned diagnostic product in the form of a polypeptide with antigenic determinants capable of specifically binding complementary antibody, the polypeptide being expressed from a stable continuous cell line. With a glycoprotein D of Herpes Simplex Virus (HSV) as the polypeptide, HSV antibody in a specimen is detected in an immunological procedure. With a glycoprotein C fragment from HSV type 2, HSV type 2 may be distinguished from HSV type 1.
