Many paths to many clones: a comparative look at high-throughput cloning methods

Area of Science:

• Molecular Biology
• Synthetic Biology
• Genomics

Background:

• Genome-scale clone resources are vital for biological research but expensive and difficult to create.
• Maximizing efficiency at each step of clone creation is essential for cost-effectiveness and scalability.
• High-throughput applications demand robust and efficient methods for generating large clone collections.

Purpose of the Study:

• To compare commercial and open-source recombinational cloning methods for creating comprehensive open reading frame (ORF) clone collections.
• To evaluate cloning strategies suitable for high-throughput settings.
• To identify the most efficient approach for generating master clone collections and subsequent expression clones.

Main Methods:

• Review and comparison of available commercial and open-source recombinational cloning techniques.
• Analysis of methods for creating master clone collections and converting them into expression clones.
• Exploration of alternative cloning strategies, including gap-repair cloning and method combinations.

Main Results:

• Recombinational cloning methods are evaluated based on their suitability for high-throughput ORF clone collection creation.
• A strategy involving a master clone collection is identified as the most efficient for producing validated source material.
• The review examines specific recombinational cloning techniques for both master clone generation and expression clone production.

Conclusions:

• The development of efficient, high-throughput methods is critical for advancing genome-scale clone resource creation.
• A master clone collection strategy offers a validated and efficient source for generating diverse expression clones.
• Recombinational cloning, including variations like gap-repair, provides versatile tools for constructing comprehensive ORF clone libraries.
