The new KAPA Library Quantification Kits available from Anachem utilise the power of Quantitative PCR (qPCR) to provide you with an accurate and sensitive method for quantifying Next Generation Sequencing (NGS) libraries.
Standard methods for quantifying NGS libraries have a variety of disadvantages. Electrophoresis and spectrophotometry measure total nucleic acid concentrations, whereas optimal cluster density or template-to-bead ratio depend on the appropriate concentration of PCR-amplifiable DNA molecules. These methods also have low sensitivity, consuming nanograms of precious samples and are not suitable for high-throughput workflows.
qPCR, however, is a highly sensitive approach which uses a minimal amount of material and eliminates the need for time-consuming and expensive titrations. It specifically quantifies only PCR-competent DNA molecules and due to its high sensitivity, allows for the accurate quantification of low concentration libraries and significantly reduces cluster density variations. It can also be automated for high-throughput applications.
"Before qPCR was adopted for library quantification, cluster density was extremely variable. Implementation of the KAPA Library Quantification Kit into our sequencing workflows resulted in a significant reduction in variability across multiple libraries, negating the need for cluster amplification titration runs".
