Protein complexity, not cost, determines which cell-free system to choose.
Cell-free protein synthesis speeds antigen production for antibody discovery.
Expression costs depend on which R&D stage fails to produce protein.
CFPS works in standard lab equipment by matching reactions to existing incubators and plate readers.
Labs must weigh cell-based and cell-free systems against protein needs, throughput, reproducibility.
Complex proteins and large-scale production often demand cell-based systems instead.
Cell-free protein synthesis outperforms E. coli for toxic, membrane, and disulfide-bonded targets.
