Figure 3. Using engineered knob proteins to enhance killing of lymphoma cells.
Panel A – Experimental setup. Lymphoma cells were incubated with the engineered knob protein Ad35K++ as reported in Wang et al. [82]. NHS is used as source of complement. Panel B – Both research and scaled preparations have equivalent efficacy. N>6. Ad35K++ (1) is a protein lot that was produced previously and used in published studies. Ad35K++ (2) is a protein made with a scalable process. The difference between rituximab + NHS and Ad35K++ + rituximab + NHS is significant (p<0.01). The difference between Ad35K++ (1) + rituximab + NHS and Ad35K++ (2) + rituximab + NHS is not significant.
