KAPA Library Quantification Kits

Overview

KAPA Library Quantification Kits contain all the reagents needed for the accurate, reliable and reproducible qPCR-based quantification of next-generation sequencing (NGS) libraries prepared for sequencing on Illumina and IonTorrent platforms. Kits include KAPA SYBR FAST qPCR Master Mix (formulated with different passive reference dyes for different qPCR instruments), a platform-specific library quantification primer premix, and a pre-diluted set of DNA standards. 

Benefits of KAPA Library Quantification Kits
  • Reliable and sensitive quantification of all sequencing-competent library molecules
  • Accurate and reproducible quantitation across a wide range of library types, concentrations, fragment length distributions and GC content
  • Accurate, equimolar pooling for multiplexed sequencing
  • Flexibility to support manual and automated high-throughput pipelines as well as PCR-free workflows
What makes KAPA Library Quantification Kits highly efficient for library quantification?

KAPA Library Quantification Kits contain KAPA SYBR FAST DNA Polymerase, which was engineered through our directed evolution technology to amplify diverse DNA fragments with similar efficiency. This is important for the amplification of heterogeneous populations such as NGS libraries. Library quantification kits containing wild-type DNA polymerases only count “easy” library molecules.*

Figure 1. KAPA SYBR FAST exhibits high-efficiency amplification and library quantification. Amplification efficiencies achieved with KAPA SYBR FAST for ten diverse amplicons, plotted against GC content. All ten amplicons were amplified with similar efficiency (within the optimal range of 95% –105%). This confirms that KAPA SYBR FAST is the ideal enzyme for the amplification of heterogenous populations of DNA fragments, such as NGS libraries.

How do KAPA Library Quantification Kits Work?

Generation of standard curve and quantification of library concentration

Six pre-diluted DNA Standards and appropriately diluted NGS libraries are amplified using platform-specific qPCR primers that target adapter sequences. The average Cq value for each DNA Standard is plotted against its known concentration to generate a standard curve. The standard curve is used to convert the average Cq values for diluted libraries to concentration, from which the working concentration of each library is calculated.

Figure 3 KAPA SYBR FAST vs. 2 competitors

Figure 3. DNA fragment size distributions for an NGS library before (grey fill) and after qPCR amplification with KAPA SYBR FAST and two competitor kits containing wild-type Taq polymerase. Reactions were performed with the following cycling protocol: 95°C for 10 min, followed by 40 cycles of 95°C for 10 sec, and 60°C for 45 sec. The KAPA SYBR FAST quantification product is representative of the template DNA (NGS library), whereas the quantification products generated with wild-type enzymes are not.

High consistency and product quality with a proven track record
  • Use of single DNA standard for all library types
  • Pre-diluted standards with very high lot-to-lot consistency

Reproducible cluster density from samples of variable quality
  • Optimal and predictable cluster densities to maximize sequencing capacity and throughput
  • Reliable results for all library types, including from low-quality FFPE DNA

Equimolar pooling for multiplexed sequencing
  • Equimolar pooling of indexed libraries, irrespective of pre-pooling library concentrations
  • Uniform distribution of reads across all the libraries in a pool
