  • Publication number: 20230152280
    Abstract: The present disclosure provides an analysis method for measuring the content of light chain-exchanged molecules in a composition containing a multi-specific antigen-binding molecule. The analysis method of the present disclosure includes the steps of: treating a composition comprising a multi-specific antigen-binding molecule and preparing a plurality of types of F(ab) fragments; and measuring the F(ab) fragments by a separation method based on electric charge or hydrophobic interactions and determining the content (content ratio) of each fragment.
