• To enable rapid testing and optimization of novel CRISPR technologies and cellular models.

Main Methods:

• Leveraged Golden Gate cloning to create the Fragmid toolkit, a modular system of CRISPR cassettes and delivery technologies.
• Developed a web portal to facilitate combinatorial vector assembly.
• Utilized a pooled screening format to assess multiple CRISPR technologies in parallel.

Main Results:

• The Fragmid toolkit enables scalable CRISPR vector assembly within days.
• Demonstrated parallel assessment of multiple CRISPR technologies for rapid optimization.
• Established Fragmid as a robust system for designing CRISPR vectors.

Conclusions:

• The Fragmid toolkit provides a combinatorial platform for efficient CRISPR vector design and assembly.
• This approach facilitates the systematic development, comparison, and dissemination of CRISPR technologies.
• Anticipated broad utility for researchers in optimizing CRISPR applications.
