| Outline of Final Research Achievements |
Developing the technique to conjugate antibody with various payload reagents, such as anticancer drug, isotopes and dye, is an important topic for evolution of antibody drug, diagnostic reagent and molecular imaging. The technical difficulty for the homogeneous conjugation to conventional IgG and IgG-derived fragments is caused by inevitable features of antibody structure. Single-domain VHH antibody, variable domain of camelid heavy chain antibody, usually has only one disulfide bond and thus is useful to obtain a homogeneous population with a fixed conjugation at a specific location. Here we report the feasibility of payload (Low molecular weight compounds, nucleic acids) conjugation with VHH antibody. The conjugate was then labeled, and its stability and functionality were characterized.
