A set of experimentally validated, mutually orthogonal primers for combinatorially specifying genetic components

Area of Science:

• Synthetic biology
• Molecular biology
• Genomics

Background:

• High-throughput gene synthesis is crucial for synthetic biology.
• Current methods rely on orthogonal primers for oligonucleotide de-multiplexing.
• A validated set of mutually orthogonal primers is a key reagent for scalable gene assembly.

Purpose of the Study:

• To present a novel set of 166 experimentally verified, mutually orthogonal 20-nucleotide primers.
• To enable the specification and assembly of a large number of unique deoxyribonucleic acid (DNA) sequences.
• To provide a valuable resource for the synthetic biology community.

Main Methods:

• Design and synthesis of 166 20-nucleotide primers.
• Experimental verification of primer orthogonality (non-interacting properties).
• Demonstration of primer utility for specifying unique gene sequences.

Main Results:

• A set of 166 20-nucleotide primers was validated to be mutually orthogonal.
• These primers can specify 13,695 unique genes.
• The primer set facilitates a scalable and modular gene assembly architecture.

Conclusions:

• The developed primer set is a significant resource for high-throughput gene synthesis.
• This resource enhances the capabilities of synthetic biology by enabling precise and efficient gene assembly.
• The primers support the creation of complex genetic constructs through a modular approach.
