The KAPA Long Range PCR system is a blend of Taq DNA polymerase and an engineered archaeal (B-family) DNA polymerase possessing proofreading capability. This two-enzyme system is designed specifically to support long-range and/or sensitive PCR, and possesses 3–4X higher fidelity than Taq polymerase.
Features and Benefits of KAPA Long Range PCR Kits
Hot-start formulation – combined with a proprietary antibody that inactivates the enzyme until the first denaturation step
Elimination of spurious amplification products and increase in reaction efficiency and sensitivity
Supplied in a 2X ReadyMix format with a loading dye, allowing direct loading of PCR products onto agarose gels with no extra steps for adding loading/tracking dye
Contain all the components required for PCR except primers and template
Figure 1. Amplification of template dilution of human genomic DNA starting with 50 ng, 10 ng, 2 ng, 400 pg per 25 µL. Amplicons were 737 bp, 1.3 kb, 3.3 kb, and 4.5 kb in lengths. 35 cycles, 72˚C extension temperature.
Figure 2. Amplification of template dilution of human genomic DNA starting with 50 ng, 10 ng, 2 ng, 400 pg per 25 µL. Amplicons were 7.5 kb, 10.5 kb, 13 kb, and 15 kb in lengths. 35 cycles, 68˚C extension temperature.

< 100 ng for genomic DNA, cDNA < 10 ng for less complex DNA
Kits may be stored for up to 18 months at -20˚C.
Kits include KAPA Long Range or KAPA Long Range HotStart DNA Polymerase (5 or 2.5 U/μL), MgCl2-free KAPA Long Range Buffer (5X), high-quality dNTP Mix (10 mM each) and MgCl2 (25 mM). KAPA Long Range HotStart is also available in KAPA Long Range HotStart ReadyMix with dye (2X), which contains DNA Polymerase, reaction buffer with loading dye, dNTPs and MgCl2 (at a final concentration of 2 mM).
