Generation and Evaluation of Bispecific Anti-TNF Antibodies Based on Single-Chain VHH Domains.

Systemic cytokine inhibition may be an effective therapeutic strategy for several autoimmune diseases. However, recent studies suggest that tissue or cell type-specific targeting of certain cytokines, including TNF, may have distinct advantages and show fewer side effects. Here we describe protocols for generating and testing bispecific cytokine inhibitors using variable domain of single-chain antibodies from Camelidae (VHH) with a focus on cell-specific TNF inhibitors.
