Problem: Formulate a response to this post from a classmate: There are various parameters that need to be carefully monitored during production in both the upstream (USP) and downstream (DSP) processing phases. Before production even begins, individuals (usually researchers or process development scientists) carefully control the selection of host cells, expression vectors, cell clones and culture medium (Gronemeyer et al., 2014). Parameters related to these selections are quality, productivity levels, growth behavior, adaptive behavior, amplification, shear stress, and post translational modification profiles.
