2085An objective of the present invention is to provide methods for promoting antigen uptake into cells by antigen-binding molecules, methods for increasing the number of times ofantigen binding by one antigen-binding molecule, methods for promoting reduction of the antigen concentration in plasma by administering antigen-binding molecules, and methods for10 improving the plasma retention of an antigen-binding molecule, as well as antigen-binding molecules that allow enhanced antigen uptake into cells, antigen-binding molecules having anincreased number of times of antigen binding, antigen-binding molecules that can promote reduction of the antigen concentration in plasma when administered, antigen-binding molecules with improved plasma retention, pharmaceutical compositions comprising the above antigen 15 binding molecules, and methods for producing them. The present inventors revealed that theabove objective can be achieved by using antigen-binding molecules that show calcium-dependent antigen-antibody reaction.(No Suitable Figure) |
