ANTI-INFLUENZA VIRUS-NEUTRALIZING ANTIBODY

摘要

The purpose of the present invention is to provide a novel antibody having high avidity and high neutralizing activity with respect to an influenza virus. The present invention provides an antibody for neutralizing the H1-type influenza virus and/or the H5-type influenza virus, which have: a heavy chain variable region having a CDR composed of a specific heavy chain first complementarity determining region (VH-CDR1), a heavy chain second complementarity determining region (VH-CDR2), and a heavy chain third complementarity determining region (VH-CDR3); and a light chain variable region having a CDR composed of a specific light chain second complementarity determining region (VL-CDR2), and a light chain third complementarity determining region (VL-CDR3).
