Area of Science:

• Molecular Biology
• Genomics
• Biotechnology

Background:

• Genomic DNA isolation is crucial for next-generation sequencing.
• Standard protocols can be time-consuming and require specific equipment.
• Pacific Biosciences (PacBio) sequencing demands high-quality, long DNA fragments.

Purpose of the Study:

• To present a simplified and rapid protocol for genomic DNA isolation.
• To evaluate the suitability of this protocol for PacBio sequencing library construction.
• To assess the quality and yield of DNA fragments obtained.

Main Methods:

• Utilized a bead-beating method for DNA extraction.
• Performed library construction for PacBio sequencing.
• Compared the developed protocol against the standard PacBio protocol.

Main Results:

• The bead-beating method provided a simple and rapid DNA isolation protocol.
• Obtained DNA fragments were of sufficient length for PacBio library construction.
• The protocol demonstrated comparable quality to the standard PacBio method.
• Potential for pathogen inactivation through simultaneous DNA fragmentation.

Conclusions:

• The bead-beating protocol is a viable, rapid alternative for genomic DNA isolation for PacBio sequencing.
• This method offers a shortcut without compromising DNA quality.
• The protocol requires no specialized equipment, enhancing accessibility.
