The Importance of High Fidelity High-fidelity PCR enzymes are valuable for minimizing the introduction of amplification
errors in products that will be cloned, sequenced, and expressed. Significant time and
effort can be saved by employing high-fidelity amplification procedures that eliminate the
need for downstream error-correction steps and minimize the number of clones that must
be sequenced in order to obtain error-free constructs or accurate consensus sequences.
Moreover, the use of high-fidelity amplification conditions is essential when analyzing
small amounts of template DNA or rare molecules in heterogeneous populations.
Amplifications employing small amounts of template DNA are especially prone to high
mutant frequencies due to PCR-generated errors in early cycles1, 2.
The ArchaeMaxx® Factor AdvantageBecause proofreading PCR enzymes can be finicky, we have improved high-fidelity PCR to
be more reliable. Our ArchaeMaxx® Polymerase-Enhancing Factor, found exclusively in our
high-fidelity DNA polymerases, improves overall PCR performance by eliminating
the inhibition of proofreading enzymes caused by incorporation of dUTP, which results
from deamination of dCTP during PCR 3. Our PCR enzymes formulated with the
ArchaeMaxx factor produce higher yields and exhibit greater target length capability.
Superior Reverse TranscriptionOur expertise in enzyme engineering also extends to reverse transcriptases. Both MMLV
and AMV reverse transcriptases possess substantial RNase H activity that degrades
RNA molecules and limits full-length cDNA synthesis and yield. For this reason, RTs that
lack RNase H activity are far superior to MMLV and other RNAse H+ RTs. Our StrataScript™
Reverse Transcriptase contains a point mutation that effectively abolishes RNase H activi-
ty, allowing more efficient production of full-length cDNA than RNase H+ RTs.

Our continuing efforts to improve the fidelity of PCR have resulted in PfuUltra™ High-FidelityDNA Polymerase, the most accurate PCR enzyme commercially available. PfuUltra DNA poly-merase is ideal for PCR cloning, site-directed mutagenesis, and anywhere sequence accuracy is critical for downstream applications.
The Most Accurate PCR Enzyme
Highest Fidelity Available
The PfuUltra™ high-fidelity DNA polymerase ø,‡ contains a
genetically engineered mutant of Pfu DNA polymerase***,‡ that
delivers 300% greater accuracy. A validated and referenced
fidelity assay4 demonstrates that PfuUltra high-fidelity DNA poly-
merase exhibits an average error rate three-fold lower than Pfu
DNA polymerase and 18-fold lower than Taq DNA polymerase,
making it the most accurate PCR enzyme available (Figure 1).
Enhanced Performance
In addition to ultra-high fidelity, PfuUltra high-fidelity DNA
polymerase exhibits superior PCR performance compared to
most PCR proofreading enzymes. The addition of our ArchaeMaxx
polymerase-enhancing factor promotes higher yields, shorter
extension times, and greater target length capability (Figure 2).
High Specificity Hotstart Version
The PfuUltra™ Hotstart DNA Polymeraseø,‡ is an antibody-mediated
hotstart formulation of PfuUltra high fidelity DNA polymerase
that provides higher specificity and reduced background.

High Fidelity for TA/UA Cloning
TA or UA cloning requires PCR products with 3'-A overhangs. We created the Easy-A™ High-Fidelity PCR CloningEnzyme to automatically add A-overhangs for quick and easy high-fidelity cloning into TA/UA vectors.
Unique Proofreading Formulation Adds A-Overhangs
Combines Cloning Efficiency with High Accuracy
The Easy-A™ high-fidelity PCR cloning enzyme ,‡,† is the only
proofreading DNA polymerase formulation to deliver high-
throughput TA or UA cloning. PCR products amplified with the
Easy-A PCR cloning enzyme can be cloned directly to T- or
U-modified vectors with high cloning efficiency and throughput
(Figure 3). But unlike Taq DNA polymerase, the Easy-A PCR
cloning enzyme exhibits proofreading activity that provides the
accuracy level of Pfu DNA polymerase.
Fidelity Without Extra Work
Adapting blunt-ended fragments amplified with proofreading
enzymes requires post-PCR addition of 3'-A overhangs prior
to the cloning step. This additional step includes a secondary
incubation with Taq DNA polymerase and requires the opening
and closing of tubes, which exposes the lab to contamination
risk. The Easy-A high-fidelity PCR cloning enzyme does not
require any post-PCR A-addition steps.
High Specificity Hotstart Formulation
The Easy-A high fidelity PCR cloning enzyme is provided as
an antibody-mediated hotstart formulation, providing higher
specificity and reduced background.
Convenient Master Mix Formulation
For the highest throughput in TA or UA cloning, choose Easy-A™
High-Fidelity PCR Master Mix ,‡,†. This 2x formulation contains the
Easy-A PCR cloning enzyme, buffer, magnesium, and dNTPs all
in one tube for faster setup and more consistent results.

We invented the high-fidelity PCR market over a decade ago with the original Pfu DNA Polymerase.Since that time, our expertise has led to improvements in high-fidelity performance with PfuTurbo®
DNA Polymerase and, more recently, PfuTurbo® Cx Hotstart DNA Polymerase. These improvementshave made high-fidelity PCR more reliable and versatile.
Robust High-Fidelity Amplification
The PfuTurbo® DNA polymerase ø,‡ is a special formulation of
cloned Pfu DNA polymerase and our ArchaeMaxx polymerase-
enhancing factor that produces increased PCR product yields
without affecting fidelity. The enhanced performance of PfuTurbo
DNA polymerase allows the use of shorter extension times,
longer targets, and lower concentrations of DNA template than
are suitable for Pfu DNA polymerase.

High Specificity Hotstart Version
The PfuTurbo® hotstart DNA polymerase ø,‡ is an antibody-
mediated hotstart formulation of PfuTurbo DNA polymerase that
provides higher specificity, reduced background, and enhanced
yield of challenging systems.
New Mutant Overcomes Uracil Sensitivity
Heat can cause deamination of cytosine to uracil in a DNA
strand. To prevent replication of such a mutation, archaeal
(proofreading) polymerases typically stop replication just before
reaching a uracil residue in the template5. In PCR, this poisoning
phenomenon can result in decreased or no product yield.
We formulated PfuTurbo ® Cx hotstart DNA polymerase**,‡ with
a novel mutant of Pfu DNA polymerase that can read through
a uracil located in the template strand without stalling. Thus
PfuTurbo Cx hotstart DNA polymerase improves the overall
reliability of high-fidelity PCR and exhibits less finicky, more
robust performance (Figure 4).
Prevent Carryover Contamination
Because PfuTurbo Cx hotstart DNA polymerase can replicate
uracil-containing DNA, it can be used to prevent carry-over
contamination. This method involves the use of dUTP in place
of dTTP in the nucleotide pool. Subsequent PCR reactions are
pre-treated with Uracil-N-glycosylase (UNG) to degrade any
dU-containing DNA left over from a previous reaction; the UNG
is then inactivated during the next denaturation step. PfuTurbo Cx
hotstart DNA polymerase incorporates dUTP in targets up to 6 kb
in length more efficiently than Taq DNA polymerase.

High Sensitivity & High Yield
Blending Taq DNA polymerase with a proofreading enzyme improves target-length capability, fidelity,and yield, but many PCR enzyme blends lack sensitivity and can lead to PCR failures. We designed thePicoMaxx™ High Fidelity PCR System to deliver the highest sensitivity and efficiency, bringing yougreater blend performance at a much lower cost per unit than other enzyme blends.
Greater Performance at a Fraction of the Cost
Sensitivity and Reliability
The PicoMaxx™ high fidelity PCR system ø,‡ is designed to provide
maximum PCR sensitivity and reliability. Sensitivity is critical for
successful amplification, especially with limited or precious sam-
ples; use of a PCR enzyme that lacks sensitivity often results in
amplification failures. Formulated with a blend of Taq and Pfu
DNA polymerases and our ArchaeMaxx polymerase-enhancing
factor, together with a specially optimized buffer, the PicoMaxx
high fidelity PCR system overcomes such PCR failures with
greater sensitivity than other PCR enzymes (Figure 5). Superior
sensitivity makes the PicoMaxx high fidelity PCR system one of
the most reliable PCR enzyme formulations available.
High Efficiency and Yield
The PicoMaxx high fidelity PCR system exhibits superior amplifi-
cation efficiencies due in large part to our patented ArchaeMaxx
factor, which eliminates dUTP that accumulates during the high
heat of PCR and can poison high-fidelity reactions.
The ArchaeMaxx factor maximizes the performance of the proof-
reading component of the blend, allowing the PicoMaxx high
fidelity PCR system to deliver higher product yields and more
reliable performance across a wide range of targets up to 10 kb.
Convenient Master Mix Formulation
For maximum sensitivity and yield with added convenience,
choose PicoMaxx™ High Fidelity PCR Master Mix ø,‡. This 2x
formulation contains the PicoMaxx high fidelity enzyme blend,
buffer, magnesium, and dNTPs all in one tube for faster setup
and more consistent results.

GC-Rich and Complex Templates
The Herculase® enhanced DNA polymeraseø,‡ meets today’s
complex PCR challenges. When you need to accurately amplify
a complex or GC-rich template, Herculase DNA polymerase will
help you succeed. A unique optimized formulation of high fidelity
Pfu DNA polymerase, Taq DNA polymerase and our ArchaeMaxx
polymerase-enhancing factor, Herculase DNA polymerase excels
in amplifying a broad range of target lengths with superior fidelity
than Taq DNA polymerase and other PCR enzyme blends6.
DMSO is provided separately as a PCR adjunct, and can be
added when amplifying difficult targets to increase product yield
and extend target-length capability (Figure 6).
Long PCR
To amplify very long targets, a blend of Taq DNA polymerase and a proofreader provides the bestresults. But not every enzyme blend can go the distance. Our EXL™ DNA Polymerase is speciallyoptimized to successfully and accurately amplify long targets up to 50 kb.
Go the Full Distance
Tackle Long Amplicons
The EXL™ DNA polymerase ø,‡ provides superior performance
in amplifying complex targets greater than 20 kb in length.
The EXL DNA polymerase is a special formulation of Pfu DNA
polymerase, Taq DNA polymerase, and our ArchaeMaxx
polymerase enhancing factor, along with a special buffer
optimized specifically for very long targets. This enzyme
blend provides robust yields and reliable amplification (Figure 7).
Amplify with Higher Accuracy
Because PCR enzymes have an intrinsic rate at which they
incorporate incorrect bases, long templates are particularly
prone to errors when amplified during PCR. Most “Long &
Accurate” PCR enzyme blends available commercially provide
only a slight increase in accuracy over Taq. EXL DNA poly-
merase provides twice the accuracy of these other blends
to ensure minimal errors in your long PCR products.

RT-PCR
Most common reverse transcriptases, including MMLV and AMV, exhibit RNase H activity,which limits yields of full-length cDNA. With StrataScript™ Reverse Transcriptase we have eliminated RNase H activity to provide greater yields of full-length transcripts.
Produce High cDNA Yields
Mutant RT Delivers Higher Yields and Sensitivity
The StrataScript™ reverse transcriptase is a Moloney murine
leukemia virus reverse transcriptase (MMLV RT) that has
been genetically modified to remove RNase H activity without
affecting the desired reverse transcriptase function. As a result,
StrataScript RT generates longer transcripts and greater
performance. We manufacture StrataScript RT to be free from
impurities, allowing for the highest possible cDNA yield (Figure 8).
StrataScript RT also provides superior sensitivity compared to
MMLV and AMV reverse transcriptases in real-time QRT-PCR
applications. StrataScript RT is the ideal choice to generate
cDNA for a variety of downstream applications including library
construction and RT-PCR.
High-Quality First-Strand Synthesis
The StrataScript™ First Strand cDNA Synthesis Kit§ employs
StrataScript RT to generate cDNA of high quality from total or
poly(A) RNA. Subsequent amplification with sequence-specific
primers yields a homogenous population of the specific cDNA
molecule of interest.

High-Quality PCR-Grade Deoxynucleotide Mix
Our dNTP mix contains 400 µl of 100 mM dNTP mix (25 mM
each of dATP, dCTP, dGTP, and dTTP), adequate for 1000-2000
standard primer-extension reactions. This mix produces high-
quality reaction products and withstands multiple freeze-thaw
cycles without compromising efficiency.
Safe, Easy PCR Cleanup
Our StrataPrep® PCR Purification Kits prepare PCR products
quickly and easily for downstream applications such as
sequencing, microarray analysis, and cloning. Following
amplification or cDNA labeling, a DNA binding solution is added
directly to the PCR tube and then transferred to a unique
microspin cup. Once bound, the DNA (cDNA) is washed and
then eluted from the column, ready for resuspension in your
application buffer of choice. For high-throughput applications,
our StrataPrep® 96 PCR Purification Kit provides the same easy
and efficient cleanup in a convenient 96-well format.
Efficient PCR Cloning
PCR-Script® Cloning Kits§, allow the efficient cloning of PCR
fragments with a high yield and a low rate of false positives.
PCR products are incubated with one of the predigested
PCR-Script cloning vectors, Srf I and T4 DNA ligase. Using
the restriction enzyme in the ligation reaction maintains a high
steady-state concentration of digested vector DNA and allows the
use of nonphosphorylated, unmodified PCR primers. The ligation
efficiency of blunt-ended DNA fragments is increased by the
simultaneous, opposite reactions of the Srf I restriction enzyme
and T4 DNA ligase on nonrecombinant vector DNA. The PCR-
Script cloning kits include the StrataPrep PCR purification kit
and also include polishing reagents to create blunt-ended PCR
products amplified with a non-proofreading enzyme.
