  • Publication number: 20240083939
    Abstract: The present invention provides efficient methods based on alteration of the protein A-binding ability, for producing or purifying multispecific antibodies having the activity of binding to two or more types of antigens to high purity through a protein A-based purification step alone. The methods of the present invention for producing or purifying multispecific antibodies which feature altering amino acid residues of antibody heavy chain constant region and/or variable region. Multispecific antibodies with an altered protein A-binding ability, which exhibit plasma retention comparable or longer than that of human IgG1, can be efficiently prepared in high purity by introducing amino acid alterations of the present invention into antibodies.

  • Patent number: 11432537
    Abstract: The present invention discloses a novel means capable of producing a blood chimeric animal in which a state of retaining blood cells originating in a heterologous animal at a high percentage is sustained for a long period of time. The method for producing a non-human animal that retains blood cells originating in a heterologous animal, according to the present invention, comprises transplanting hematopoietic cells of a heterologous animal into a non-human animal, in which hematopoietic cells the function of a gene that acts on the hematopoietic system is modified, The gene that acts on the hematopoietic system is, for example, Lnk gene, When a medium to large mammal is used as a recipient, the survival rate of hematopoietic cells originating in a heterologous animal is dramatically increased such that blood chimerism of 10% or more can be maintained even in a 16 month old animal.
