FIGURE 4.
Design of experiments (DoE) for optimizing PfCyRPA production in High Five cells. Response surface models for PfCyRPA protein titer (mg/L) from screening experiments (A) and optimization experiments (B). (C) Cell growth and viability kinetics in optimal conditions identified by DoE. Improvement of PfCyRPA protein titer (mg/L) in optimal conditions identified by DoE vs. standard condition (i.e., cultures at 27°C and no supplementation). DoE images were obtained using MODDE® 12.1 Pro software (Sartorius). Data in bar graphs are expressed as mean ± standard deviation (relative to three technical replicates, n = 3). Abbreviations: TOI, time of infection; Lip, lipids; Poly, polyamines; α-keta, α-ketoglutarate; AOx, antioxidants.
