Kanter et al. developed a cell-free system for highly effective production of a fusion protein consisting of a single chain Fv antibody fragment (scFv) connected to granulocyte-macrophage colony-stimulating factor (GM-CSF), a vaccine of B-cell lymphoma.366 Lu et al. described a CFPS overexpressing a domain of pandemic H1N1 influenza virus for potentially and broadly protective influenza vaccines.367 Besides bacterial systems, eukaryotic cell-free systems can express complex vaccines. Here, CSF2 is linked to B-cell non-Hodgkin lymphoma.
