Guide and selection support
Kits for NGS library quantification are used to accurately determine the quantity and quality of DNA libraries prior to sequencing. This is a crucial step to ensure reproducible and robust results in NGS workflows.
The choice of suitable kits depends on measurement accuracy, compatibility with various library types, and the required analysis time. The type of quantification method—such as fluorometric or qPCR-based—is also important.

Application and Benefits
NGS library quantification kits are specifically designed to measure the DNA concentration and quality of NGS libraries. They are used in the workflow after library construction and before sequencing to ensure optimal sample amounts. Precise quantification improves the reproducibility and efficiency of next generation sequencing and helps prevent overloading or underloading the sequencing platform.
Selection Criteria
Accuracy and sensitivity of the measurement method are key factors in kit selection. Fluorometric methods are frequently used as they specifically detect target DNA and offer high sensitivity. Alternatively, qPCR-based kits can be used, which also provide information on library amplifiability. Additionally, compatibility with various library types and sequencing platforms, as well as sample preparation effort and turnaround time, should be taken into account.
Variants and Measurement Principles
There are primarily fluorometric kits, which use DNA-specific dyes, and qPCR-based kits, which utilize amplification to determine accurate concentrations. Fluorescence measurements are straightforward and fast, while qPCR methods enable more complex analyses with additional quality information. The choice depends on the workflow and requirements for detection limits and accuracy.
Calibration and Maintenance
Quantification is generally performed using standards and control samples, which should be regularly used for calibration and validation. For qPCR-based kits, instrument maintenance and appropriate storage of reagents are also important. In general, careful handling is essential to ensure reproducible results.
Limitations of Application
NGS library quantification kits are optimized for the analysis of NGS-specific DNA libraries and are not intended for general DNA or RNA quantification outside this context. Interfering factors such as contaminants or incomplete library construction can affect measurement accuracy. Some kits do not provide information on library quality, so additional QC steps may be advisable.
