KAPA RNA HyperPrep Kit
KAPA RNA HyperPrep Kit is designed for both manual and automated NGS library construction from 1– 100 ng of purified total, rRNA-depleted, or poly(A)-enriched RNA. The protocol is applicable to a wide range of RNA-Seq applications, including:
- targeted RNA-Seq;
- whole transcriptome;
- gene expression analysis of high- and low-quality RNA samples (e.g., extracted from FFPE tissue);
- single-nucleotide variation (SNV) discovery; and
- splice junction and gene fusion identification.
This kit is not compatible with small RNAs <100 bp in length.
The KAPA RNA HyperPrep Kits utilize novel chemistry that enables the combination of enzymatic steps and fewer reaction purifications, resulting in a truly streamlined solution for the preparation of high-quality RNA-seq libraries. The strand-specific workflow is flexible—supporting library construction from lower-input amounts and degraded samples. Kits contain all reagents required for RNA enrichment (if performed) and library preparation, with the exception of KAPA Adapters (available separately).
The KAPA RNA HyperPrep Kit for Illumina sequencing contains all of the buffers and enzymes required for the rapid construction of stranded RNA-Seq libraries
from 1 – 100 ng of purified total, rRNA-depleted, or poly(A)- enriched RNA via the following steps:
- fragmentation using heat and magnesium;
- 1st strand cDNA synthesis using random priming;
- combined 2nd strand synthesis and A-tailing, which converts the cDNA:RNA hybrid to double-stranded cDNA (dscDNA), incorporates dUTP into the second cDNA strand for stranded RNA sequencing, and adds dAMP to the 3′ ends of the resulting dscDNA;
- adapter ligation, where dsDNA adapters with 3′ dTMP overhangs are ligated to library insert fragments; and
- library amplification, to amplify library fragments carrying appropriate adapter sequences at both ends using high-fidelity, low-bias PCR. The strand marked with dUTP is not amplified, allowing strand-specific sequencing.
The kit provides KAPA Pure Beads for reaction cleanups, along with all of the enzymes and buffers required for cDNA synthesis, library construction and amplification, but does not include RNA or adapters. KAPA Adapters are sold separately.
Reaction buffers are supplied in convenient formats comprising all of the required reaction components. This minimizes the risk of RNase contamination, ensures consistent and homogenous reaction composition, and improves uniformity among replicate samples. Similarly, a single enzyme mixture is provided for each step of the library construction process, reducing the number of pipetting steps.
In order to maximize sequence coverage uniformity and to maintain relative transcript abundance, it is critical that library amplification bias be kept to a minimum. KAPA HiFi DNA Polymerase has been designed for low-bias, high fidelity PCR, and is the polymerase of choice for NGS library amplification1-4. The KAPA RNA HyperPrep Kit includes KAPA HiFi HotStart ReadyMix (2X) and Library Amplification Primer Mix (10X) for library amplification.
