Cell-free protein expression utilizes the molecular machinery inherent in bacterial, wheat germ or rabbit reticulocyte lysates to directly synthesize proteins in vitro. The process allows rapid, high-yield protein production without the constraints of cell growth and viability. Cell-free protein expression has gained popularity in the biopharmaceutical industry for protein screening and production of toxic or unstable proteins. It helps accelerate the discovery and development of novel biologics.
According to Coherent Market Insights, The global Cell-Free Protein Expression Market is estimated to be valued at USD 341.4 Mn in 2025 and is expected to exhibit a CAGR of 7.3% over the forecast period 2025 to 2032.
