The modubodies contain a domain from the heavy chain variable region of an antibody (VH), a domain from the light chain variable region of an antibody (VL) and bind monospecifically to an antigen. The modubodies further contain a domain from the constant region of antibodies. The modubodies can be used for diagnostic or therapeutic purposes."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Monospecific polypeptide reagents","description":"The present invention relates to a novel antigen-binding protein construct or “modubody”, which contains at least three functional single domain modules of an antibody.
