Process Analytics - Percent Dissolved Oxygen PAT To Optimize Recombinant Growth Factor 
Continuous monitoring system for a protein refolding reaction to provide consistency in product quality and process performance across batches. A small-scale bioreactor (3 L) is used to understand the impact of aeration for refolding recombinant human vascular endothelial growth factor (rhVEGF) in a reducing environment. A reverse-phase HPLC assay is used to assess product quality. The goal in understanding the oxygen needs of the reaction and its impact to quality, is to make a product that is efficiently refolded to its native and active form with minimum oxidative degradation from batch to batch. Because this refolding process is heavily dependent on oxygen, the % dissolved oxygen (DO) profile is explored as a PAT tool to regulate process performance at commercial manufacturing scale. A dynamic gassing out approach using constant mass transfer (k(L)a) is used for scale-up of the aeration parameters to manufacturing scale tanks (2,000 L, 15,000 L). The resulting DO profiles of the refolding reaction show similar trends across scales and these are analyzed using rpHPLC.

Process Analytics - Real Time Noninvasive Spectroscopy w Automated Sampling
Noninvasive spectroscopic methods such as Raman, near infrared, and dielectric spectroscopy provide real-time information on cell culture and fermentation processes, combined with periodic aseptic batch sampling, thereby allowing hands-off, contamination-free sampling; automated sample scheduling; automated at-line analysis of whole broth and cell-free samples; increased sampling frequencies; increased sampling reproducibility;  and increased data reliability.

​Process Analytics - Drug Substance: Process Step Description + Desired Outcome of Unit Operation
1. Cell Culture to generate cells grown in Bioreactor. Desired outcome is PAT measurement and control of critical mass of protein-producing cells. 

2. Fermentation to produce desired protein in Bioreactor. Desired outcome is PAT measurement and control of target protein concentration.

3. Homogenization (bacteria only) to rupture cells. Desired outcome is PAT measurement and control of amount energy necessary to break cell membranes to expose the protein.

4. Harvest to separate protein from cell matter . Desired outcome is PAT measurement and control of centrifuge to separate proteins from cell matter.

5. Purification to further separate protein from other impurities using chromatography columns, filters. PAT measurement and control to purify protein while sustaining within solution without physical disruption of the protein.

​Process Analytics - Drug Product: Process Step Description + Desired Outcome of Unit Operation
1. Formulation is adjusted to add compounds to stabilize and adjust potency. Desired outcome is PAT measurement and control to ensure formulation is potent and product is an effective stable biopharmaceutical.

2. Fill/Finish in order to segregate into separate doses (freeze ifnecessary). Desired outcome is PAT measurement and control of appropriate fill level and properly dosed and frozen vials.

3. Package/Seal in order to ensure appropriately sealed and boxed vials with appropriate labelling. Desired outcome is PAT measurement and control of capping and labeling.

4. Cold Chain from manufacturer to vendor by consistent control by maintain temperature during transport. Desired outcome is PAT measurement and control of  insulated packaging and refrigerated vehicles to ensure effective therapy is delivered to patient.
