Library preparation is a critical step that involves the conversion of nucleic acids into a format suitable for sequencing. This process is essential for obtaining high-quality sequencing data and can significantly impact the accuracy and reliability of downstream analyses.

Library preparation typically involves several key steps: fragmentation of nucleic acids, end repair, adapter ligation, and amplification (Figure 1). These steps enable the generation of a library that can be sequenced using various NGS platforms. The choice of library preparation method can vary based on the type of nucleic acid being analyzed (DNA or RNA), the quantity and quality of starting material, and the specific requirements of the sequencing project.

Recent Advancements

Recent studies have highlighted innovative strategies to enhance library preparation efficiency and quality:

• Targeted Sequencing: A novel method involving genomic DNA circularization allows for targeted sequencing with fewer steps and reduced PCR amplification requirements. This approach simplifies library preparation by integrating capture oligonucleotides directly into the circularized DNA, facilitating efficient targeting without extensive amplification.
• High-Diversity Libraries: Advances in viral vector barcoding have enabled the generation of high-diversity plasmid libraries that can assess genetic function in vivo. This method allows for the production of millions of uniquely barcoded plasmids in a single reaction, significantly enhancing throughput and application versatility in functional genomics.
• Quality Control Improvements: Enhanced quality control measures during library preparation have been developed to ensure high fidelity in sequencing results. For instance, using Bioanalyzer systems allows researchers to accurately assess library quality before sequencing, ensuring that only high-quality libraries are processed.
