Design Notes

By connecting the variable regions of the heavy and light chain of an anti-GPA33 antibody with a short, flexible GGGGS linker (BBa_K3117028), the scFv retains it's antigen-binding ability and is much smaller than a conventional antibody. The SpyCatcher attached to the scFv belongs to the SpyTag/SpyCatcher system, of which the sequence is derived of the FbaB protein in the bacteria Streptococcus pyogenes. Once it comes into contact with its corresponding other part, the SpyTag (BBa_K3117015), they bind covalently (Hatlem et al., 2019). This allows our part to be used in a modular manner in combination with other molecules carrying the SpyTag. The sequence contains a C-terminal His-Tag (BBa_K3117005) for easy purification and detection. Secretion of the protein into the periplasm is ensured by a pelB sequence (BBa_K3117012).
