Lucentis Fab is a monoclonal antibody fragment (Fab) derived from the same parent mouse antibody as bevacizumab (bevacizumab). It is much smaller than the parent molecule and has been affinity matured to provide stronger binding to VEGF-A. https://www.creativebiolabs.net/Anti-Human-VEGF-therapeutic-Antibody-Fab-Fragment-ranibizumab-13764.htm
