A novel miniaturized fluid array device enables high-throughput cell-free protein synthesis (CFPS), significantly reducing reagent use and analysis time for gene discovery and drug screening.

Area of Science:

Biotechnology
Molecular Biology
Synthetic Biology

Background:

High-throughput recombinant protein production is crucial for gene discovery and functional studies.
Current methods using bacterial cells are often costly and difficult to scale.
Existing cell-free protein synthesis (CFPS) instruments lack the throughput for large-scale gene discovery.

Purpose of the Study:

To develop a miniaturized fluid array device for high-throughput cell-free protein synthesis (CFPS).
To enable simultaneous expression of up to 96 proteins for gene discovery applications.
To demonstrate the device's utility in drug screening and reduce analysis time.

Main Methods:

Design and implementation of a 96-unit miniaturized fluid array for CFPS.

Expression of various proteins, including β-glucuronidase and β-galactosidase, using the device.

Demonstration of drug screening feasibility by measuring enzyme inhibition without protein harvesting.

Main Results:

The fluid array device achieved a >100-fold reduction in reagent consumption compared to commercial CFPS instruments.
Protein expression yields were significantly enhanced, with β-glucuronidase showing up to an 87-fold increase.
High concentrations of expressed proteins were achieved, e.g., 5.5 μg/μL for β-galactosidase.
Drug screening analysis time was reduced from days to hours.

Conclusions:

The miniaturized fluid array device offers a scalable and cost-effective solution for high-throughput protein synthesis.
This technology accelerates gene discovery by enabling rapid production and analysis of multiple proteins.
The device facilitates efficient drug screening, significantly reducing experimental timelines.
