Dhinakar Kompala gave this 90 second talk showcasing the latest innovation of Sudhin Biopharma Company, at the 2nd annual meeting of National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL) in the auditorium of the National Academy of Sciences in Washington D.C.
Sudhin Biopharma receives a Quick Start Project award of $1.5 Millions from National Institute for Innovation in Manufacturing Biopharmaceuticals (NNIMBL), with in-kind cost-share commitment of another $0.5 millions from a Tier 1 industrial member of NIIMBL. The project, titled “Scale-up Studies on Single Use Settlers for Clarifying Cell Culture Broth,” aims to develop a disposable plastic device for clarifying cell culture broth from a single-use bioreactor. This process is currently done by centrifugation and/or using depth filters. However, removing cells through these methods becomes challenging at high cell densities and at large scale. Through this single-use disposable settler device, cells can be separated from the secreted protein product to produce a significantly clarified product harvest stream.
Sudhin Biopharma Co. will produce and deliver 6- inch, 12-inch and 24-inch diameter single use disposable plastic settlers as part of the project. These devices will also be demonstrated as selective cell retention devices to remove dead cells and cell debris through the settler’s top effluent and to return the live and productive cells to a continuous perfusion bioreactor, which can then be operated at high cell densities, viabilities and productivities over months-long culture duration.
Dhinakar Kompala presents an invited talk on "Novel compact cell settler for high cell density perfusion bioreactor cultures of microbial (and mammalian) cells" at the BioProduction Congress in Convention Centre Dublin, Ireland.
Sudhin Biopharma Co. publishes its first peer-reviewed article: Freeman, Cassandra A., Premsingh S.D. Samuel, and Dhinakar S. Kompala, "Compact cell settlers for perfusion cultures of microbial (and mammalian) cells", in a special issue of Biotechnology Progress 33:913-922 (2017). DOI 10.1002/btpr.2533
Dhinakar Kompala presents a 2 minute introduction to Sudhin’s innovation at Small and Medium Enterprises Innovation Showcase during the Launch or Kickoff National Meeting of the newly funded National Institute for Innovation in Manufacturing Biopharmaceutics, of which Sudhin Biopharma just joined as a SME member.
Second beta testing of our Stainless Steel Compact Cell Settler has commenced at a large biopharmaceutical company in Sweden. More devices are available for beta testing by other interested companies.
Sudhin Biopharma Company has been awarded a National Science Foundation (NSF) Small Business Innovation Research (SBIR) Phase I grant for $225,000 to conduct research and development (R&D) work on demonstrating the power of our compact cell settler to achieve high cell densities and productivities in continuous perfusion bioreactor cultures of recombinant mammalian cells.
With this new grant funding, we plan to culture (i) recombinant Chinese hamster ovary cells and (ii) murine hybridoma cells in continuous perfusion bioreactors attached with our 4" or 6" compact cell settler and demonstrate that dead cells and cell debris can be removed selectively via the settler top effluent while the live and productive cells are recycled continuously to the bioreactor. Our patent-pending compact cell settler technology is a more efficiently scaled version (with much smaller footprint and higher settling capacity) of the proven "inclined settler" technology, which has been used successfully in commercial production of some therapeutic biologics. We expect to reproduce for the mammalian cell cultures our recently obtained excellent results for the smaller and hence more challenging yeast Pichia pastoris cells, demonstrating very high cell densities and productivities in continuous perfusion bioreactor for over two months without any membrane clogging or protein sieving challenges seen with other cell retention devices.
"The National Science Foundation supports small businesses with the most innovative, cutting-edge ideas that have the potential to become great commercial successes and make huge societal impacts," said Barry Johnson, Director of the NSF’s Division of Industrial Innovation and Partnerships. "We hope that this seed funding will spark solutions to some of the most important challenges of our time across all areas of science and technology."
Beta testing of our Novel Compact Cell Settler has commenced at a large biopharmaceutical company in USA. More devices are available for beta testing by other interested companies.
