Abstract: Certain aspects of the present invention are directed to new fully human fusion partner cell lines called human Karyochi cells, and to methods for making them. Human Karyochi cells are then fused with human antibody-secreting lymphoid cells to make fully human hybridomas called Karyochi-based hybridomas, which likewise secrete fully human monoclonal antibodies. Human Karyochi cells are made by isolating a donor nucleus that is substantially free of cytoplasm from either a first malignant B-lymphocyte cell line or a normal B-lymphocyte, and transferring the donor nucleus into the cytoplasm of a recipient cell from a second T- or B-lymphoid cell line. With time the nuclei synchronize and fuse to form the chimeric Karyochi fusion partner cell line. Nuclear transfer can be accomplished using intra-cytosolic nucleus injection or by impact-induced nucleus administration.
