  • Publication number: 20230183299
    Abstract: The present disclosure provides materials and methods for cell-free expression of epitopes for immunotherapy applications. In particular, the present disclosure provides materials and methods for expressing concatenated epitopes using a cell-free protein synthesis platform for high throughput, large scale, and unbiased epitope screening and the generation of multi-epitope vaccines.

  • Patent number: 11639514
    Abstract: A portable fluidic platform for rapid and flexible end-to-end production of recombinant protein biologics includes a bioreactor system hosting stable and robust cell-free translation systems that is fluidically integrated with modular protein separation functionalities (e.g., size exclusion, ion exchange or affinity chromatography systems) for purification of the cell-free expressed product and which are configurable for process-specific isolation of different proteins, as well as for formulation. The bioreactor utilizes lysates from engineered eukaryotic (e.g., yeast) or prokaryotic (e.g., bacterial) strains that contain factors for protein folding and posttranslational modifications. Combination of various purification modules on the same fluidic platform allows flexibility of re-routing for purification of different proteins depending on specific target requirements.
