  • Patent number: 9200335
    Abstract: A bioreactor that combines the steps of recombinant expression and separation of a biological product by binding the secreted biological product with a resin, discarding the nutrient medium and eluting the biological product as a concentrated solution, eliminating the steps of sterile filtration and volume reduction. The method also allows loading of resin for column-purification, eliminating all steps of perfusion process and maintaining a sink condition of a toxic product in nutrient medium to optimize productivity of host cells. The instant invention also allows harvesting of solubilized inclusion bodies after the cells have been lysed and refolding of proteins inside the bioreactor.

  • Publication number: 20150253022
    Abstract: A single-pass HVAC systems to isolate zones and to maintain a required clean air quality standard is provided that operates by producing a positive pressure in all zones, while exhausting on a minimal quantity of air required by law. The zones are kept clean by a recirculating fan filter in each zone. The exhaust air is used to exchange heat with incoming air to conserve energy further.
