For module four, the teams were assigned different academic articles for literature review focusing on the same topic, viscosity behavior for mAbs. The goal was for the students to answer the potential causes of high viscosity. Team 1 was given an article by Tilegenova et al. about a potential cause for high viscosity in some antibodies, while Team 2 was assigned an article by Wang et al. about the effect of some excipients on lowering the viscosity of mAbs. Having the teams present two different articles allowed each team to fill in knowledge gaps and provide clarity to confusing subjects. These articles engaged in more complicated modeling, experimentation, and computations than previous literature review assignments, allowing students to understand the topic further. Students learned that the high viscosity of antibody drugs could be caused by attractive protein-protein interactions that can induce large cluster formation.
