Abstract: 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.

Abstract: The present invention provides a cancer cell-specific anti-podoplanin antibody or an antigen-binding fragment thereof having an epitope in a Thr85-containing region of an amino acid sequence of human podoplanin represented by SEQ ID NO: 1, the Thr85 having a sialylated O-glycan added thereto.

Abstract: The present invention provides a cancer microenvironment-targeting anti-podocalyxin antibody or antigen binding fragment thereof.

Abstract: Disclosed are: an anti-podoplanin antibody which has a high binding activity and a high effector activity and has low antigenicity in humans or mice; and others. Specifically disclosed are: a chimeric antibody comprising an anti-podoplanin antibody for which an epitope is a polypeptide comprising the amino acid sequence set forth in SEQ ID NO:1 (excluding rat NZ-1 antibody having a heavy chain comprising the amino acid sequence set forth in SEQ ID NO:2 and a light chain comprising the amino acid sequence set forth in SEQ ID NO:3), and a heavy chain complementarity determining region and a light chain complementary determining region of the anti-podoplanin antibody; and others.
