MOLÉCULE SE LIANT À DES ANTIGÈNES POUR LA PROMOTION DE LA CLAIRANCE À PARTIR DU PLASMA DE L'ANTIGÈNE COMPRENANT UN DOMAINE RÉCEPTEUR-FIXATEUR DE LA CHAÎNE SACCHARIDIQUE
Disclosed are an antigen-binding molecule containing a sugar chain receptor-binding domain and having a weak antigen-binding activity in the pH of early-stage endosome compared to the antigen-binding activity in the pH of plasma； a pharmaceutical composition containing the antigen-binding molecule； and a method for producing these. Use of the antigen-binding molecule of the invention enables to promote uptake of an antigen into a cell and increase the number of antigens that a single antibody molecule can bind. Administration of the antibody enables to reduce the number of antigens in plasma more and more and improve pharmacokinetics of the antibody.
