  • 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.

  • Patent number: 7321828
    Abstract: Interative, preferably computer based iterative processes for generating synthetic compounds with desired physical, chemical and/or bioactive properties, i.e., active compounds, are provided. During iterations of the processes, a target nucleic acid sequence is provided or selected, and a library of candidate nucleobase sequences is generated in silico according to defined criteria. A “virtual” oligonucleotide chemistry is chosen and a library of virtual oligonucleotide compounds having the selected nucleobase sequences is generated. These virtual compounds are reviewed and compounds predicted to have particular properties are selected. The selected compounds are robotically synthesized and are preferably robotically assayed for a desired physical, chemical or biological activity. Active compounds are thus generated and, at the same time, preferred sequences and regions of the target nucleic acid that are amenable to oligonucleotide or sequence-based modulation are identified.
