Since the early days of bioprocess engineering shear associated protein aggregation was believed to be a real thread for proteins causing a decrease in production yield accompanied by higher costs. Although some research indicated that moderate shear rates do not aggregate proteins, the scientific consensus today is still not aligned. Recent results suggested that elongational forces, very similar to shear, can unfold proteins. Hence, there is a strong demand for a technical solution to describe extraordinary high shear rates and investigate their impact on protein aggregation, to answer this unsolved mystery in bioprocess engineering.
