    摘要: The present invention provides a method for measuring in vitro pharmacokinetics of a molecule, the method including steps of: (a) contacting a molecule with a cell expressing FcRn in an aqueous medium to allow the cell to take up the molecule to be an uptake amount higher than 0.068 pmol/2 × 10 5 cells, in which step (a) has at least one feature selected from the following (i) to (iii): (i) a period of the contact of the molecule with the cell is 5 hours or more; (ii) the cell after the contact with the molecule is not washed under acidic conditions; and (iii) the cell expresses a target of the molecule on a surface of the cell; and (b) measuring in vitro pharmacokinetics of the molecule, in which the molecule contains an FcRn-binding domain, and the like.

    摘要: Disclosed is an antibody capable of binding to Claudin-6 (CLDN6) which is expressed on the surface of a cell membrane. The antibody can recognize human CLDN6 occurring on the surface of a cell membrane in its native form, and has a cytotoxic activity (e.g., ADCC activity and a CDC activity) against a cancer cell line which expresses human CLDN6 at a high level. A conjugate of the antibody and a toxin has an inhibitory activity on the cell proliferation of a cancer cell line which expresses human CLDN6 at a high level. The expression of human CLDN6 is not observed in a normal tissue, but is increased in a tumor tissue (e.g., pulmonary adenocarcinoma, gastric cancer, ovarian cancer). The anti-CLDN6 antibody is expected to be highly accumulated in tumor in which human CLDN6 has been expressed at a high level, and therefore can be used as an extremely effective anti-tumor agent.
