What is an Fc Fused VHH Antibody?

Fc fused VHH antibodies, also known as nanobodies, are single-domain antibodies derived from camelids such as llamas and alpacas. The small size of these antibodies—typically around 15 kDa—makes them exceptional candidates for therapeutic applications. When fused with an Fc region, they gain additional stability, extended half-life, and improved binding capabilities.

Benefits of Fc Fused VHH Antibodies

• High Affinity and Specificity: These antibodies can bind to targets that are often inaccessible to conventional antibodies.
• Stability: The Fc fusion enhances thermal and enzymatic stability, making them suitable for various assays and therapeutic uses.
• Easy Production: VHHs can be rapidly produced and easily purified from simple expression systems, which is beneficial in research settings.
