摘要： An antibody or antigen-binding fragment thereof is disclosed. The antibody or antigen-binding fragment thereof binds to HER2 expressed on a cancer cell or a fragment of the HER2. A HER2-targeting agent containing any of the antibody or antigen-binding fragment thereof, and a pharmaceutical composition containing the HER2-targeting agent are disclosed.

摘要： The present invention provides a method for producing an antibody against podocalyxin expressed specifically in cancer cells. The method includes a step of introducing a nucleic acid encoding all or a portion of podocalyxin into cells expressing a cancer cell-specific sugar chain structure to cause cancer cell-specific podocalyxin or a portion thereof to be expressed therein, a step of immunizing a non-human mammal with the cancer cell-specific podocalyxin or portion thereof to obtain antibodies, and a step of purifying the antibodies by primary screening using purified cancer cell-specific podocalyxin or a portion thereof.
