Combinatorial DNA Library Services

Let DNA Building Experts Speed Up your Research Process!

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 services to accelerate the build phase of your “design, build, exam & learn” development cycle so you can efficiently move through the process of optimizing or developing bio-based products.

You can use our custom-built combinatorial DNA libraries in a variety of applications across many disciplines of life sciences, from plant biology to drug development. The following lists three major areas of combinatorial DNA library applications:

Synthetic Biology

  • Metabolic Pathway and Microbial Strain Engineering: screen and optimize your synthetic molecular pathways to develop the most efficient metabolic gene circuits for chemical, drug, and biofuel production.
  • Genome Engineering: screen high-throughput libraries of synthetic nuclease- or CRISPR/Cas9-based constructs for highly effective genome editing.

Protein Engineering

  • Create new multi-domain proteins for structural or functional screening.
  • Optimize protein function through directed evolution.
  • Generate recombinant protein or chimeric antibody libraries for high-throughput screening for biologic drug discovery and development.

Gene Expression Regulation

  • Determine the optimal combination of promoter, ribosome binding site, terminator, and other regulatory elements for your construct or expression system.
  • Create a library of reporter-gene constructs for systematic promoter analysis.
  • Express any gene of interest under the control of different promoters, e.g. for inducible or tissue-specific manipulation of lethal or developmentally vital genes.
