Cell-Free Protein Synthesis Will Replace Cell-Based Manufacturing for 50% of Biologic Drugs Within a Decade

Cell-free systems extract the transcription-translation machinery from cells and run it in a test tube. No cell growth, no contamination risk, no batch variability. You add DNA template and energy source; proteins come out. Yields have improved 1000-fold in the last decade (Silverman et al., 2019, Nature Reviews Genetics).

The advantages are transformative: reactions complete in hours not weeks, toxic products don't kill the production system, non-natural amino acids incorporate readily, and the entire process is automatable. But the field has been stuck in "it works for research proteins" mode.

Hypothesis: Cell-free protein synthesis will capture >30% of the biologic drug manufacturing market by 2035, starting with rapid-response vaccines, peptide therapeutics, and personalized cancer vaccines where speed-to-product matters more than cost-per-gram.

Prediction: The first cell-free manufactured biologic drug will receive FDA approval by 2029, likely a rapid-response pandemic vaccine or a personalized neoantigen cancer vaccine.
