  • Patent number: 10975157
    Abstract: The invention provides antibodies immunoreactive with human OX40 and methods of using the same. The antibodies are reactive with a portion of the C-terminus of the human OX40 protein that includes amino acids 266-277. The antibodies are useful for detecting OX40 protein expression in human tissue samples, including by immunohistochemistry, immunofluorescence, or immunoblot.
    Type: Grant

    Date of Patent: April 13, 2021
    Assignee: Ventana Medical Systems, Inc.
    Inventors: Yifei Zhu, Zhiming Liao, Robert Pytela
  • Patent number: 10377814
    Abstract: The invention provides a rabbit-derived immortal B-lymphocyte capable of fusion with a rabbit splenocyte to produce a hybrid cell that produces an antibody. The immortal B-lymphocyte does not detectably express endogenous immunoglobulin heavy chain and may contain, in certain embodiments, an altered immunoglobulin heavy chain-encoding gene. A hybridoma resulting from fusion between the subject immortal B-lymphocyte and a rabbit antibody-producing cell is provided, as is a method of using that hybridoma to produce an antibody. The subject invention finds use in a variety of different diagnostic, therapeutic and research applications.
