  • Patent number: 8859278
    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.

  • Patent number: 8497138
    Abstract: In one aspect the present invention provides a method for selecting a cell or cell colony which produces a polypeptide of interest, comprising a) providing a medium comprising cells and a detection agent, wherein the detection agent is associated with a detectable signal and the detection agent is capable of binding to the polypeptide of interest; b) providing a solid phase having a capture agent disposed thereon, wherein the capture agent is capable of binding to the polypeptide of interest; c) contacting the medium with the solid phase; d) detecting the signal associated with the detection agent; and e) selecting a cell or cell colony associated with the signal, wherein presence of the signal is indicative of a cell or cell colony which produces the polypeptide of interest.

  • Patent number: 8486657
    Abstract: It is disclosed herein that antibodies specific for preproproteins or preproteins, which are synthesized by certain types of cells or tissues, can be used in immunohistochemistry assays to discriminate between the intracellular component of the protein (including the preproprotein, preprotein and/or proprotein forms of the protein) from the secreted component of the same protein. Accordingly, provided herein is an immunohistochemical method for specific detection of the intracellular form of a protein in a biological sample using an antibody specific for the preproprotein or preprotein form of the protein. In particular examples, the protein is albumin or an immunoglobulin light chain. Also disclosed herein are preproprotein-specific ore preprotein-specific antibodies that can be used to detect specific cell types, tissue lesions or other pathological foci and metastases by IHC. In particular, antibodies that specifically bind human preproalbumin, but do not bind the secreted form of albumin are disclosed.

  • Patent number: 8409818
    Abstract: The invention provides kits and methods for detecting or monitoring the number of cells in sample. The cell comprises a cell surface associated protein (CSAP) comprising a cytoplasmic (cytosolic) and an extracellular (ecto) domain. The kit comprises: (i) a chromatographic device; and (ii) a CSAP-binding agent. The method comprises: (i) optionally contacting the sample with an agent capable of lysing or permeabilizing CSAP bearing cells; (ii) contacting the sample with a CSAP-binding agent that binds to the cytoplasmic domain of the CSAP; and (iii) directly or indirectly evaluating the level or presence of bound CSAP in the sample.
