An Accelerated Protein Engineering Workflow Utilizing Linear DNA In A Cell-Free Expression System

This content is brought to you by Integrated DNA Technologies, a Danaher Operating Company.

Accelerating protein engineering often hinges on overcoming slow, iterative design-build-test cycles tied to cloning, transformation, and cell growth. A cell-free expression approach using linear DNA reframes this process, enabling rapid protein production without the constraints of living systems. By combining synthetic gene fragments with an E. coli–based transcription–translation system, researchers can move from DNA template to measurable protein output in hours, not days. Experimental results highlight how template design, such as promoter choice, flanking regions, and terminator inclusion, directly impacts expression yield, offering practical guidance for optimization. The ability to generate functional proteins quickly, even from minimal constructs, supports high-throughput screening and streamlined workflow automation.

Explore how this approach can reduce bottlenecks and bring greater speed and flexibility to protein engineering pipelines.
