Background:

Mate-pair reads are essential for scaffolding contigs in de novo genome sequencing.
Preparing mate-pair libraries can be complex and costly, even with commercial kits like Illumina's Nextera Mate Pair Sample Prep Kit.

Purpose of the Study:

To optimize the Nextera Mate Pair Sample Prep Kit protocol for reduced cost, enhanced library yield, and improved fidelity.
To provide practical suggestions for improving mate-pair library preparation using this kit.

Main Methods:

Modified the manufacturer's protocol by adjusting tagmentation conditions.
Intensively sheared DNA to reduce library insert length.
Utilized Illumina HiSeq sequencing with over 150 cycles.

Main Results:

The modified protocol demonstrated potential for cost reduction and increased library yield and fidelity.
Specific modifications led to improved outcomes in mate-pair library preparation.

Conclusions:

The optimized protocol offers a more efficient and cost-effective approach to mate-pair library preparation.
The findings provide valuable insights for researchers performing de novo genome sequencing and assembly.
