Guide and selection support
Next Generation Sequencing (NGS) is a molecular biology method for the parallel analysis of millions to billions of DNA fragments. It allows for rapid and detailed evaluation of genetic material in research and diagnostics.
When selecting NGS solutions, factors such as sample type, desired read length, throughput requirements, and compatibility with sample preparation systems are key. Consumables and data analysis must also be considered.
LabFinder provides a structured overview of NGS products, including sequencing platforms, quantification kits for libraries, and automated sample preparation systems. This makes it easy for users to find suitable NGS technologies for their laboratory needs.
Application and Benefits
Next Generation Sequencing (NGS) is a high-throughput technology for parallel sequencing of DNA fragments. By simultaneously capturing large numbers of short DNA sequences, genomic information from many samples can be acquired quickly and in detail. NGS is used in genomics research, molecular diagnostics, personalized medicine, and basic biological research.
Selection Criteria
Important factors when choosing NGS systems and accessories include throughput (number of reads sequenced in parallel), sequence read length, depth of coverage, and compatibility with sample preparation and workflow. Consumables such as library quantification kits also influence data quality. Ergonomics and automation can make laboratory processes more efficient.
Variants and Measurement Principles
NGS platforms typically rely on the principle of massive parallel sequencing, where clonally amplified DNA or single DNA molecules are sequenced in flow cells. Technical differences exist with respect to sequencing chemistry and the type of signal detection. Sequences are usually comprised of short reads from 50 to 400 bases.
Calibration and Maintenance
Regular calibration and maintenance of sequencing platforms ensure consistent measurement accuracy and device availability. Consumables such as reagent kits should be stored and used in accordance with the manufacturer's instructions to assure comparability of data.
Limitations of Application
NGS technology is optimized for comprehensive mapping of large genomic regions, but short reads can make it difficult to reconstruct longer and complex structures. The interpretation of large volumes of data also requires intensive bioinformatic analysis and specialized expertise.

Frequently asked questions
How does Next Generation Sequencing (NGS) work?
NGS is based on massively parallel sequencing of many short DNA fragments that are analyzed simultaneously in a flow cell. DNA is often clonally amplified or directly sequenced as single molecules, generating millions to billions of sequence data points per run.
What types of NGS platforms are available?
NGS platforms mainly differ in the sequencing chemistry and signal detection methods used. All rely on massive parallelization, but read length and throughput vary depending on the system.
What should I consider when selecting NGS systems?
Key factors are throughput, read length, data quality, and compatibility with sample preparation systems and consumables. Automated workflow integration and available bioinformatics analysis options are also important.
What are the limitations of Next Generation Sequencing?
NGS produces short sequence reads, which can make reconstructing complex genome regions challenging. In addition, large-scale data analysis requires significant effort and specialized expertise.
