Machine-guided rapid decision-making on quality of viruses as products and for viral clearance determination
Develop a computational means to integrate results of rapid viral titer assays (e.g., qPCR, ddPCR, optical imaging, probe-capture methods) to best match results of high precision determination of functional titer.

Industry Need
Develop a model that can better predict functional titer from lower-cost methods of analysis compared to using transmission electron microscopy (TEM) images of viruses
Solution
Carnegie Mellon University and Sartorius aim to develop a computational workflow to integrate results of rapid viral titer assays to best match the outcomes of high precision determination of functional titer.
The two organizations will incorporate and validate their methods by using machine learning (ML) approaches.
Experiments will include:
Analysis of physical and functional virus titers at various concentrations, from bioreactor supernatant in the presence of cell lysate or other confounding matrices
Determination of physical characteristics of infected cells
This project will determine the workflow that optimizes analytical assay reproducibility and repeatability and will predict gaps in knowledge that may limit product analysis.
Impacts
Decrease decision-making time and provides reduced use of costly assays
Create computational assessment of rapid viral titer assays (e.g., qPCR, ddPCR, optical imaging, probe-capture methods) to best predict functional titer of viruses
Provide evaluation methods that are applicable during viral production (e.g., bioreactor stage) to facilitate early decision making
