Utility analyses of AVITI sequencing chemistry.

Area of Science:

• Genomics and Molecular Biology
• Next-Generation Sequencing Technologies

Background:

• DNA sequencing is vital in modern biology, with massively parallel sequencing driving advances.
• High-throughput short-read sequencing faces challenges in accuracy, options, and cost.

Purpose of the Study:

• To comparatively analyze Element Biosciences' AVITI and Illumina's sequencing chemistries.
• To evaluate performance in DNA and RNA short-read, and synthetic long-read applications.

Main Methods:

• Comparative analysis of AVITI and Illumina NextSeq 550 for short-read DNA/RNA.
• Evaluation of AVITI and Illumina NovaSeq 6000 for synthetic long-read RNA and targeted single-cell RNA sequencing.

Main Results:

• AVITI demonstrated significantly higher per-sequence quality scores for both DNA and RNA short-read applications.
• AVITI showed substantially lower error rates: 89.7% for PCR-free DNA and 32.5% for RNA quantification.
• Both platforms performed comparably for synthetic long-read sequencing, with AVITI having a marginally lower error rate.

Conclusions:

• The AVITI platform shows potential as a competitive option for high-throughput short-read sequencing.
• AVITI offers improved accuracy and lower error rates compared to Illumina's NextSeq 550.
