Fully automated library preparation builds a new matrix for companion diagnostics of tumors

News source: Release time:[2024-03-07]

The first consensus on "Automation and Standardization of Next-Generation Sequencing in Clinical Practice", led by the Medical Laboratory Engineering Branch of the Chinese Society of Biomedical Engineering, was published in the "Chinese Journal of Biomedical Engineering" at the end of 2023. With the development of tumor companion diagnostics and the improvement of library preparation automation, Feishuo Biotech, as a molecular diagnostic enterprise integrating R&D, production, and sales of in vitro diagnostic reagents, has developed a series of molecular detection products for tumor diagnosis, typing, monitoring, and screening based on the NGS technology platform. Actively following the consensus, Feishuo Biotech has launched a dedicated automated solution for NGS library preparation, efficiently realizing the automation and standardization of processes such as nucleic acid sample preparation, library preparation, and library quality control, further improving the gene testing application chain, enhancing overall strength and competitiveness in the user's overall solution.

Fully automatic library preparation and evaluation machine


To improve the efficiency of companion diagnostics, our company uses the Human EGFR/KRAS/BRAF/HER2/ALK/ROS1 gene mutation detection reagent kit (semiconductor sequencing method) based on NGS fully automatic library preparation and evaluation machine for evaluation and constructs an expanded high-throughput automated tumor companion diagnostic testing platform application. To comprehensively improve the quality and efficiency of the testing process, the automation process of this platform is optimized with module design and upgraded bench layout to match different library preparation throughputs, significantly improving library preparation efficiency. With more than 90% reduction in manual operations while ensuring high-quality library preparation, it frees up the hands of laboratory personnel, improves work efficiency, effectively reduces and avoids the possibility of human errors, thereby ensuring precise, reliable, stable, and efficient results.

Quality analysis


Quantitative analysis of library concentration shows that the uniformity of automated library preparation is superior to manual operation. The peak graph of library fragment analysis shows a clear main peak with no impurities. Capillary electrophoresis results show that the main peak range of the library is 200-300 bp.
