sparQ Fast Library Quant Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention or treatment of a disease.

Description

sparQ Fast Library Quant Kit provides rapid and accurate quantification of libraries prepared for sequencing on Illumina® NGS platforms. Accurate quantification of the number of amplifiable library molecules prior to loading onto a flow cell is a critical step in the NGS workflow and it ensures optimal cluster generation and cost-effective use of sequencing capacity. The sparQ Fast Library Quant Kit uses real-time qPCR (qPCR) to specifically quantify the number of library molecules that possess the appropriate adapter tag at each end.

Complete library quantification solution with unmatched convenience

sparQ Fast Library Quant workflow


Complete library quantification solution with unmatched convenience

Reactions are prepared by simply adding standard or diluted library sample. Optimized protocols with fast cycling condition are provided for both 10 μl or 20 μl reaction volumes. Following qPCR run, a standard curve is constructed which is then used to determine the concentrations of each unknown diluted library sample.

qPCR as the most accurate method for library quantification

Comparison of library quantification methods


Comparison of library quantification methods

qPCR is the most sensitive and precise method for library quantification as it measures only DNA fragments containing the appropriate adapter sequences on both ends. Other methods based on spectrophotometry, fluorometry, or microfluidic electrophoresis are prone to variabilities and inaccuracies due to factors such as sensitivity to contaminants or measurement of unsequenceable fragments.


<
>

  • qPCR only quantifies library fragments with adapters attached at both ends
  • Other methods can lead to overestimation of library concentration


Equivalent performance with 50% faster run time

Performance comparison


Performance comparison

Results from sparQ and Roche KAPA Library Quant Kits were highly correlated. Concentrations of six different diluted libraries were determined using either the sparQ Fast Library Quant Kit on Q or the Roche KAPA Library Quantification Kit on Bio-Rad CFX following the manufacturer’s recommended protocol. Run times, including melt curves, were 40 minutes for sparQ and 80 minutes for KAPA.

  • Highly correlated library quantification results obtained
  • 50% faster run time compared to Roche KAPA Library Quant Kit


Lot-to-lot consistency of sparQ DNA Standards

High consistency of sparQ DNA Standards


High consistency of sparQ DNA Standards

sparQ Fast Library Quant Kits are manufactured with high lot to-lot consistency. Concentrations of diluted libraries with low GC (library 1), high GC (library 2), or balanced GC-content (library 3) were determined using 3 different lots of sparQ DNA Standards. Each library sample was tested in quadruplicate reactions with each lot of sparQ DNA Standards. Standard deviations of average quantification values were all <0.13 pM.

  • Rigorous quality control to ensure consistent, reliable performance
  • Pre-diluted sparQ DNA Standards with excellent lot-to-lot consistency

Instrument Capability

The sparQ Fast Library Quant Kit is optimized for the Q qPCR instrument which uses a magnetic induction technology to rapidly heat samples coupled with fan forced air for cooling to acquire data more rapidly.
