Next-generation sequencing (NGS) has transformed the landscape of molecular biology, enabling rapid, high-throughput analysis of genetic material. From prenatal diagnostics to agricultural applications, NGS technology facilitates detailed genetic analysis, assisting in diagnosing genetic diseases, selecting quality breeds, and even supporting scientific research in universities and industrial laboratories. In this blog, we explore the diverse applications of NGS technology, the specific requirements of various customer groups, and the importance of robust library construction tools in achieving successful outcomes.
1. NGS in Prenatal Diagnostics and Genetic Disease Detection
NGS is widely adopted in prenatal diagnostics and genetic disease detection, providing precise insights into genetic abnormalities early on. This field typically serves two main customer groups:
- IVD Companies and Medical Inspection Centers: These institutions have the necessary medical qualifications to conduct diagnostic tests for genetic conditions.
- Hospitals: Many hospitals with in-house laboratories perform NGS-based diagnostics for prenatal testing and genetic disease screening.
Samples and Automation: Blood and body fluids are the primary sample types for genetic testing in prenatal diagnostics. While there is some level of automation in library construction for these tests, a significant portion still requires manual handling due to the specific protocols of each institution.
Product Requirements: The primary demand is for DNA library construction kits, with some applications requiring multiplex amplification and single-cell genome amplification for precise analysis.
Process Adaptation: While NGS technology integrates well into existing workflows, some customization is often required to ensure compatibility with each institution’s protocols, particularly in more specialized medical laboratories.
2. NGS for Agricultural Breeding and Quality Selection
In agriculture, NGS technology aids in selecting high-quality breeds and improving genetic diversity in crops and livestock. Customer groups in this domain include:
- Breeding Services Companies: These entities, including major corporations, utilize NGS to identify desirable genetic traits.
- Breeding Industry Corporations: Major agricultural companies leverage NGS to improve crop and livestock quality.
- Certification and Inspection Units: Agencies that inspect livestock and crop genetics rely on NGS for accurate genetic profiling.
Sample Types: Agricultural applications mainly involve single sample types from specific species, such as cattle, sheep, rice, and corn, focusing on a uniform evaluation system.
High Automation in Library Construction: Unlike clinical applications, agricultural NGS processes often involve a higher level of automation, as companies deal with large numbers of samples and require consistent data for quality control.
Product Needs: DNA and RNA library construction kits are essential, with a focus on high success rates in sequencing. For companies focusing on RNA analysis, additional tools are necessary for the quantification and verification of genetic traits.
3. Scientific Research and Publication: Expanding the Boundaries of Knowledge
Universities, scientific research units, and research institutions extensively utilize NGS for diverse studies, from studying plant genetics to analyzing microbial communities in various ecosystems. Customer groups include:
- Scientific Research Units and Universities: These institutions rely on NGS for exploratory studies, often requiring flexibility in sample types and methodologies.
- Research Outsourcing Services: Some scientific institutions outsource sequencing and data analysis to third-party NGS service providers.
Sample Diversity and Universal Compatibility: Unlike other applications, research institutions handle a wide variety of samples, including plant, animal, blood, and soil samples. Thus, NGS products in this domain must offer universal compatibility across different sample types and be adaptable to various protocols.
Automation and Database Building: With large sample volumes, research institutions emphasize automation in database construction, reagent consistency, and ease of use. These institutions often experiment with streamlined processes to reduce manual labor.
Product Requirements: Research applications necessitate versatile DNA and RNA library construction kits, with customization options for specialized studies. Apparent library construction kits may also be used, offering researchers a universal toolkit adaptable to different sample types and experiment goals.
4. Key Platforms Supporting NGS Technology
NGS platforms like PacBio and Nanopore provide unique capabilities for sequencing. Each platform has strengths that serve specific research needs:
- PacBio Platform: Known for long-read sequencing, the PacBio system offers high accuracy and is suitable for complex genomic applications. It includes models like the RS2 and Sequel series, with capabilities ranging from 10-15 kb read lengths to a maximum of 1.5 Gb per SMRT cell.
- Nanopore Platform: Known for scalability, the Nanopore platform (e.g., MinION, GridION, PromethION) provides real-time sequencing capabilities with the ability to achieve read lengths up to 4 Mb, allowing flexibility in sequencing large genomes.
