Abstract: This invention relates to the production of recombinant proteins in mammals' milk. Particularly, this invention relates to an expression system which when transgenically incorporated into a mammal permits the female species of that mammal to produce the desired recombinant protein in or along with its milk. This invention also relates to the transgenic mammal that produces the desired recombinant product in its milk.

Abstract: The invention uses the power of display selection methods to screen libraries of human immunoglobulin genes from nonhuman transgenic animals expresing human immunoglobulins. Such screening produces unlimited numbers of high affinity human antibodies to any target of interest.

Abstract: The invention provides methods of diagnosis using human antibodies. The methods are particularly useful for analyzing human samples containing HAMA or heterophilic antibodies. A human antibody can bind to an analyte in such samples without binding to HAMA or heterophilic antibodies present in the sample. The methods can be effected using a sandwhich format among others.

Abstract: The invention relates to transgenic non-human animals capable of producing heterologous antibodies and transgenic non-human animals having inactivated endogenous immunoglobulin genes. In one aspect of the invention, endogenous immunoglobulin genes are suppressed by antisense polynucleotides and/or by antiserum directed against endogenous immunoglobulins. Heterologous antibodies are encoded by immunoglobulin genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, one or more transgenes containing sequences of unrearranged heterologous human immunoglobulin heavy chains are introduced into a non-human animal thereby forming a transgenic animal capable of functionally rearranging transgenic immunoglobulin sequences and producing a repertoire of antibodies of various isotypes encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g.

Abstract: The invention relates to transgenic non-human animals capable of producing heterologous antibodies, i.e., antibodies encoded by immunoglobulin heavy and light chain genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, transgenes encoding unrearranged heterologous human immunoglobulin heavy and light chains are introduced into a non-human animal thereby forming a transgenic animal capable of producing antibodies encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody.

Abstract: The invention relates to transgenic non-human animals capable of producing heterologous antibodies of multiple isotypes. Heterologous antibodies are encoded by immunoglobulin heavy chain genes not normally found in the genome of that species of non-human animal. In one aspect of the invention, one or more transgenes containing sequences that permit isotype switching of encoded unrearranged heterologous human immunoglobulin heavy chains are introduced into a non-human animal thereby forming a transgenic animal capable of producing antibodies of various isotypes encoded by human immunoglobulin genes. Such heterologous human antibodies are produced in B-cells which are thereafter immortalized, e.g., by fusing with an immortalizing cell line such as a myeloma or by manipulating such B-cells by other techniques to perpetuate a cell line capable of producing a monoclonal heterologous antibody.
