Design Notes

By connecting the variable regions of the heavy and the light chain of an anti-CD3 antibody with a short GGGGS linker (BBa_K3117004), the scFv retains it's antigen-binding ability and is much smaller than a conventional antibody. Thus, it is well suited as part of a fusion protein with another effector. The SpyTag attached to the scFv belongs to the SpyTag/SpyCatcher system and is one part of the FbaB protein of Streptococcus pyogenes. Once it comes into contact with its corresponding other part, the SpyCatcher (BBa_K3117016), they bind covalently. This allows our part to be used in a modular manner in combination with other molecules carrying the SpyCatcher. The sequence contains a C-terminal His-tag (BBa_K3117005) for easy purification and detection. Secretion of the protein is ensured by an Igk leader (BBa_K3117006). When the protein passes the membrane, this leader segment is cleaved off.
