How to Balance High-Titer Processes with Consistent Quality?

          The high cell culture process (XD®) is a continuous process in which both cells and product are retained in a stirred-tank bioreactor using suspension mammalian culture. This is accomplished using a retention system: Fresh medium is continuously supplied, and metabolic byproducts are withdrawn and discarded through the retention system. XD® provides a controlled environment that leads to consistent product quality in terms of bioactivity, glycosylation pattern, and other product characteristics. Moreover, XD® technology is independent…
