RNA Polymerases and NTPs
T7 R&DNA™ Polymerase
T7 R&DNA™ Polymerase is a mutant form of the wild-type T7 RNA Polymerase that:
• Readily incorporates 2′-dNTPs and other 2′-modified-dNTPs, as well as canonical NTPs.
• Produces “RNA” of mixed rNMP/2′-dNMP or rNMP/2′-modified-NMP composition.
• Produces modified “RNA” transcripts that are resistant to RNase A and related RNases.
• Uses the same transcription promoters as the wild-type T7 RNA polymerases.
The DuraScribe® T7 Transcription Kit for making 2′-fluorine-modified RNA that is completely
resistant to RNase A is also available (see p. 8).

DuraScribe® T7 & SP6 Transcription Kits
The DuraScribe® T7 and SP6 Transcription Kits* produce 2′-Fluorine-modified RNA transcripts—
called DuraScript® RNA—that are completely resistant to RNase A. DuraScribe T7 and SP6
RNA Polymerases are mutant forms of T7 and SP6 RNA Polymerases that efficiently incorporate
2′-Fluorine-dCTP (2′-F-dCTP) and 2′-Fluorine-dUTP (2′-F-dUTP), as well as ATP and GTP into
full-length transcripts. They use the same promoters as wild-type T7 and SP6 RNA polymerases.
The presence of the 2′-F-dC and 2′-F-dU nucleotides render DuraScript RNA completely resistant
to RNase A and related ribonucleases. A standard DuraScribe T7 reaction produces about 50 µg of
DuraScript RNA.
Use DuraScript RNA for:
• RNAi, ribozyme, and antisense RNA studies.
• In situ hybridization.
• Ribonuclease protection assays.

concatamers are produced.
CircLigase™ II ssDNA Ligase can be used for:
• Production of ssDNA templates for rolling-circle replication or rolling-circle transcription
experiments.
• Production of ssDNA templates for RNA polymerase and RNA polymerase inhibitor assays.
The enzyme offers the following benefits:
• It circularizes ssDNA molecules >15 bases, including cDNAs, without the need for oligo bridges or
splints.
• Virtually no linear or circular concatamers are produced under standard reaction conditions.
*Covered by issued and/or pending patents. See www.EpiBio.com/legal.

Figure 1. CircLigase™ II ssDNA Ligase
converts linear ssDNA into closedcircular ssDNA. A 71-base ssDNA oligo
was converted to a circular DNA form
in a reaction containing MnCl2 and
CircLigase II ssDNA Ligase. Lane 1, DNA
markers; lane 2, 71-base linear ssDNA
oligo; lane 3, circularization proceeds
through an adenylated intermediate;
lane 4, closed-circular ssDNA reaction
product.
Figure 2. Preparation of a circular
ssDNA library. 5′-end-tagged and
fragmented T7 D111 genomic DNA was
heat-denatured and then circularized by
incubating in 33 mM Tris-acetate pH 7.6,
66 mM KOAc, 2.5 MnCl2, and 1 M betaine
for 2 hours at 60°C in the presence
or absence of 400 U of CircLigase™ II
enzyme, as indicated. Reaction products
were incubated with exonuclease I and
exonuclease III to digest linear DNA
prior to PCR amplification with primers
complementary to each tag. Reaction
products were visualized by SYBR® Gold
staining.

RNA Amplification Kits
TargetAmp™ RNA Amplification Kits for Expression Microarray Studies
The TargetAmp™ RNA Amplification Kits are the most robust kits for producing labeled target aRNA
(also called cRNA) from small samples for transcription profiling or expression microarray studies.
Features include:
• High yield/low input of RNA.
• Fast reactions.
• Linear RNA amplification process.
• High-quality microarray results on Affymetrix® GeneChip®, Illumina® BeadArray and other
commercial and spotted arrays.
• Evaluation kit program is available.
TargetAmp™ 1-Round RNA Amplification Kit reactions are single-tube reactions that can be
completed in about 6 hours. The TargetAmp 1-Round Kit reactions produce microgram quantities of
aRNA from 25 to 500 ng of input total RNA.
TargetAmp™ 2-Round RNA Amplification Kits are the only RNA amplification kits that enable
microarray studies from a single cell. The TargetAmp 2-Round Kit reactions produce microgram
quantities of aRNA from 10 to 500 pg of input total RNA.
MessageBOOSTER™ cDNA Synthesis Kits For Small-Sample RT-PCR Studies
The MessageBOOSTER™ cDNA Synthesis Kits amplify the poly(A) RNA contained in a total RNA
preparation and then convert the amplified RNA to cDNA that is ready for PCR or qPCR.
• Reproducibly detect even low-abundance transcripts from as little as one cell.
• Get hundreds of qRT-PCRs from as little as one cell.
• Collect samples less often and archive valuable samples.
• One-day reaction.
• Linear RNA amplification process preserves the relative abundance of transcripts present in the
sample.
Three MessageBOOSTER Kits are available that enable the researcher to work with purified total RNA,
compromised or partially degraded total RNA, or to perform a MessageBOOSTER cDNA synthesis
reaction directly from a cultured-cell lysate without having to purify RNA.
RiboMultiplier™ Sense-RNA Amplification Kit
The RiboMultiplier™ Kit utilizes a unique terminal tagging process to produce high yields of amplified
sense RNA (sRNA).
• Produce micrograms of sense RNA from as little as 10 ng of input total RNA.
• Sense RNA produced has excellent 3′/5′ ratio.
• Sense RNA produced demonstrates excellent correlation on microarrays with MAQC TaqMan® data.
