  • Publication number: 20160207982
    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.
