KAPA SYBR® FAST qPCR Kits
Containing the first DNA polymerase evolved for real-time PCR.
KAPA SYBR® FAST qPCR Kits are designed for the highest performance in real-time PCR. Kits contain a novel DNA polymerase engineered through a process of molecular evolution - the result is a unique enzyme, specifically evolved for qPCR using SYBR® Green I dye chemistry.
The KAPA SYBR® DNA Polymerase was engineered to perform optimally in stringent real-time qPCR reaction conditions, exhibiting dramatic improvements to signal-to-noise ratio (fluorescence), cycle threshold (Ct), linearity, and sensitivity. The KAPA SYBR® DNA Polymerase and proprietary buffer system enhances the amplification efficiency of difficult templates, including both GC-rich and AT-rich templates.
I lead genome-wide studies on RNA (gene expression and alternative splicing) and DNA (SNPs and copy number variation) and real-time PCR is a key player for validating our results. I switched to the KAPA SYBR® FAST qPCR Kit from Kapa Biosystems because I noticed a significant improvement in PCR reaction efficiency - the kit works very nicely for the vast majority of primers we design without optimization and for all our various applications. This universality makes our real-time PCR assays very fast to establish and our results more reliable.

High performance gene expression analysis
The improved speed, processivity and robustness of KAPA SYBR® FAST qPCR Kits results in consistently high amplification efficiencies required for accurate relative quantification. To demonstrate the high performance of KAPA SYBR® FAST for gene expression analysis, the reaction efficiencies obtained for ten commonly used housekeeping genes in the human breast cancer cell line, MCF-7, were compared. The KAPA SYBR® FAST qPCR Kit achieved consistently high amplification efficiencies (95 – 104%) across all ten genes, despite differences in amplicon length.
No bias in amplification efficiency relative to GC content (44.2 – 62.5%) or amplicon length (86 – 249 bp) is observed with KAPA SYBR® FAST. Ampliﬁcation efficiencies achieved for ten housekeeping genes with the KAPA SYBR® FAST Universal qPCR Kit, plotted against GC content (top) or amplicon length (bottom). The reaction efficiency achieved for each of the ten genes fell within the optimal range of 95 –105%, independent of the nature or length of the amplicon.
Typical results achieved with KAPA SYBR® FAST qPCR Kits in the ampliﬁcation of housekeeping genes for gene expression analysis. Two housekeeping genes (ActB and HPRT1) were ampliﬁed from log-fold serial dilutions of MCF-7 cDNA (100 ng - 10 pg/reaction) using the KAPA SYBR® FAST Universal qPCR Kit (green) or the Invitrogen Express SYBR® GreenER™ Kit (blue). Linear ampliﬁcation plots (top) demonstrate earlier Ct scores and greater baseline subtracted ﬂuorescence for both the ActB and HPRT1 genes with the KAPA SYBR® FAST Kit. Calculated reaction eﬃciencies (bottom) conﬁrmed that the consistently high performance required for accurate expression quantitation is achievable with the KAPA SYBR® FAST qPCR Kit (EActB = 100% and EHPRT1 = 104%). Eﬃciencies obtained with the Invitrogen Express SYBR® GreenER™ Kit were sub-optimal for both housekeeping genes (EActB= 107% and EHPRT1= 115%).
Superior signals, Ct values, and reaction efficiencies
The high performance of the KAPA SYBR® FAST qPCR kit can been seen when compared to other leading Fast qPCR Mater Mixes. KAPA SYBR® FAST consistently produces higher signal, earlier Cts, and 100% reaction efficiencies.
A 290 bp fragment of the human beta-actin gene was amplified from a set of five 10-fold dilutions of human genomic DNA (20 ng to 2 pg) using KAPA SYBR® FAST qPCR Master Mix (green) or fast qPCR competitor kits (ABI Power SYBR® Green qPCR Master Mix, orange; Qiagen QuantiFast qPCR Master Mix, purple; and Invitrogen SYBR® GreenER™ qPCR SuperMix, blue). Reactions were performed according to each competitors’ suggested protocol on an ABI Prism® 7900 HT real-time cycler.
High speed and high performance
High speed does not compromise performance with the KAPA SYBR® FAST qPCR kits. As can been seen from the amplification plots and standard curves there is no loss in performance between fast and conventional cycling conditions even with complex targets.

Human coagulation factor V (F5) was amplified from log-fold dilutions of human genomic DNA (20 ng-2 pg) using KAPA SYBR® FAST qPCR Master Mix, with fast cycling protocol, or with conventional cycling conditions. There is no loss in performance between fast and conventional cycling conditions even with complex targets. Although the proprietary antibody hot start is activated after 20 seconds at 95°C, 3 min initial activation at 95°C is recommended for optimal denaturation of complex targets.
Highest performance on Roche LightCycler® 480
KAPA SYBR® FAST qPCR Master Mix (2x) is specifically formulated for the highest performance on the Roche LightCycler® 480 instrument. A dramatic loss in performance of the Roche LightCycler® 480 SYBR® Green I Master kit was observed as the extension time at 72°C was reduced from 6 sec to 1 sec. There was no loss in performance of the KAPA SYBR® FAST qPCR Master Mix (2x) Kit optimized for the Roche LightCycler® 480.
Human B-actin (290 bp) was amplified from log-fold dilutions of human genomic DNA (20 ng to 2 pg) using KAPA SYBR® FAST qPCR Master Mix (2x) Roche LightCycler® 480 or Roche LightCycler® 480 SYBR Green I Master kit (Roche). Comparisons were performed according to the competitor protocol A: Roche protocol: 95°C, 5 min followed by 40 cycles of 95°C, 10 sec; 60°C, 15 sec; 72°C, 6 sec; or B: KAPA SYBR® FAST Protocol: 95°C 3 min followed by 40 cycles of 95°C, 10 sec; 60°C, 15 sec; 72°C, 1 sec.
Highest fluorescence and earliest Ct
The KAPA SYBR® FAST qPCR kit displays the highest fluorescence and earliest Ct values from a range of AT and GC-rich amplicons.
Human B-actin, human coagulation factor V (F5), and HPRT1 targets were amplified from 20ng (5900 copies) of human genomic DNA on an ABI Prism® 7900 HT sequence detection system. Values represent an average of triplicates.
