CRISPy-web: An online resource to design sgRNAs for CRISPR applications

Area of Science:

• Molecular Biology
• Genomics
• Bioinformatics

Background:

• CRISPR/Cas9 is a revolutionary genome editing technology.
• The system, derived from prokaryotic adaptive immunity, uses Cas9 endonuclease.
• Designing single guide RNAs (sgRNAs) is crucial for Cas9-mediated editing.

Purpose of the Study:

• To develop an accessible web tool for designing sgRNAs.
• To enable sgRNA design for any user-provided microbial genome.
• To facilitate genome engineering in non-model organisms.

Main Methods:

• Development of CRISPy-web, a web-based application.
• Interactive genome region selection for sgRNA scanning.
• Incorporation of off-target match analysis.
• Graphical display and export of sgRNA sequences.

Main Results:

• CRISPy-web provides an intuitive interface for sgRNA design.
• The tool supports user-provided microbial genomes.
• Off-target analysis is integrated into the design workflow.
• sgRNA sequences are readily exportable.

Conclusions:

• CRISPy-web simplifies sgRNA design for microbial genomes.
• The tool expands CRISPR/Cas9 applications to non-model organisms.
• Web accessibility removes the need for command-line expertise.
