摘要
作为一种快速高效的体外蛋白合成手段,无细胞蛋白表达体系(Cell-free Protein Synthesis,CFPS)一直以来就被广泛应用于基础生物学领域的研究。与传统的基于细胞的体内表达体系相比,CFPS突破了细胞的生理限制,其可调控性强、对毒性蛋白的耐受力高,使得许多很难在体内合成的复杂蛋白在体外顺利表达。近年来随着研究人员不断对CFPS进行优化,通过简化制备工艺、开发价格低廉的能量再生系统、稳定底物供应、促进蛋白正确折叠等方式,成功研发出生产效率高、成本低廉、反应体积大的表达体系。凭借其高通量和大规模的蛋白表达优势,CFPS为解决生物制药领域中面临的难题提供了新的解决思路,并成功地应用于高通量药物筛选、大规模生产重组蛋白药物、个体化定制肿瘤疫苗等领域,显示出其在生物制药领域的重要应用潜力。
Cell-free protein synthesis（CFPS） systems have been widely used for decades as a rapid and efficient tool in fundamental biology. Without the requirements for cell viability and growth, CFPS systems have distinct advantages over in vivo systems for protein production. Recently, great efforts have been made to further optimize CFPS systems to produce proteins at high yields, reduced cost and increased scale, including simplifying extract preparation procedures, developing new energy regeneration systems to protein synthesis, stabilizing substrate supply and promoting protein folding. Nowadays, CFPS systems are emerging as a powerful platform for industrial and highthroughput production of protein therapeutics, providing an alternative solution to solve problems in biopharmaceutical engineering. Moreover, CFPS systems have been successfully applied to high-throughput drug screening, large-scale protein therapeutics production, custom-made anti-cancer vaccines. These achievements highlight that CFPS systems have great potential for a wide range of applications in biopharmaceutical engineering in the future.
