Methods of preparing a population of cells that express paired TCR alpha and beta chain sequences, or an antigen-binding portion thereof, are also disclosed. Isolated pairs of TCR alpha and beta chain sequences and isolated populations of cells prepared by the methods are also disclosed.

Abstract: The present inventors discovered that by forming a large immune complex comprising antigens containing two or more antigenic binding units (epitopes) and two or more antigen-binding molecules (for example, antibodies), elimination from the plasma of the antigens containing two or more antigenic binding units can be accelerated. Moreover, they found that by using this characteristic and by further using antigen-binding molecules having an ion-dependent antigen-binding activity, elimination of the antigens can further be accelerated and the above problem can be solved.
