Combinatorial DNA Library Assembly Services

GenScript Builds Your Design Faster!

Combinatorial DNA Library Assembly Services

Combinatorial DNA libraries are powerful, high-throughput tools used in a variety of applications, including metabolic pathway and microbial strain engineering for optimizing biological systems and producing high-value chemicals, biofuels, pharmaceuticals, and sustainable food. Combinatorial DNA libraries, or combinatorial assembly libraries, are made as a set of predefined DNA parts strategically assembled in a specific arrangement.

Built on our advanced, high-throughput platforms and world-renowned expertise in gene synthesis, GenScript offers comprehensive combinatorial DNA library assembly services for various downstream screening needs to help accelerate your metabolic pathway and microbial strain engineering process.

Arrayed Library Assembly
Example Workflow

Over the last several years, GenScript has partnered with researchers in both industry and academia to build sophisticated combinatorial DNA libraries. These highly-customized libraries were used to develop new drugs, enzymes, or to discover novel gene functions and networks. The following is one example of such successful partnerships:
