  • Compositions and methods for detecting and quantifying host cell protein in cell lines and recombinant polypeptide products
    Patent number: 11519912
    Abstract: Monoclonal and polyclonal antibodies that bind hamster phospholipase B-like 2 are provided. Also provided are methods for detecting and quantifying hamster phospholipase B-like 2, for example, in recombinant polypeptide preparations, as well as kits for carrying out such methods. Methods of screening or selecting host cell lines or recombinant polypeptide-expressing cell lines that express low levels of hamster phospholipase B-like 2 are also provided.
    Type: Grant
    Filed: March 7, 2018
    Date of Patent: December 6, 2022
    Assignee: Genentech, Inc.
    Inventors: Feny Gunawan, Yi-Chun Hsiao, Denise C. Krawitz, Margaret S. Lin, Martin Vanderlaan, Rajesh Vij, Inn H. Yuk, Judith Zhu-Shimoni
