Product information "ALLin™ Isothermal 1Step RNA Amplification Kit"

ALLin™ Isothermal 1Step RNA Amplification Kit enables detection of < 5 target RNA molecules in a short time of 30 minutes without the use of PCR cycler.  An RT5 Mix, the blend of a thermostable reverse transcriptase and highly efficient RNase Inhibitor is included in the kit to initially synthesize cDNA from RNA templates.

The cDNA is amplified by Bst polymerase. Kit includes a 2X master mix with optimized high-performance buffer, dNTPs and a recombinant Bst Polymerase large fragment having strong 5’ - 3’ strand displacement activity and efficient 5’-3’ polymerase activity working at 55-70°C. The Polymerase has neither 5’ - 3’ nor 3’ - 5’ exonuclease activity and retains only minor reverse transcription activity.

The kit also includes PCR water; only templates and primers have to be supplied by the user. Quantitative Fluorescent Dye, 20X is included for an optional use, for a real-time detection in FAM channel on any qPCR cycler. ALLin™ Isothermal 1Step RNA Amplification Kit is a tool of choice for isothermal amplification of RNA templates and such applications like RT LAMP, with an additional advantage of higher temperature reactions, what makes amplification of complex and GC rich templates more efficient.

Technical characteristics of Bst DNA Polymerase large fragment:

  • Strong 5’ - 3’ strand displacement activity
  • 5’-3’ polymerase activity
  • No 5’ - 3’ exonuclease activity
  • No 3’ - 5’ exonuclease (proofreading) activity
  • Minor reverse transcriptase activity
  • Optimal amplification temperature is 65°C.
  • Working temperature range is 55-70°C.
  • The Bst enzyme is inactivated in 10 minutes at 80°C.
  • RT5 Mix includes thermostable reverse transcriptase (modified MMuLV) working at high temperatures and a thermostable RNase inhibitor protecting template RNA from degradation.
  • Optimal 1Step RT amplification reaction time is 30 minutes, if needed, the reaction can be performed 30 to 60 minutes.
  • Quantitative Fluorescent Dye has the excitation max. at 482 nm and emission max. at 512 nm.

The use of this product in certain applications may be covered by patents. The user has to analyse all applicable Limited Use Label Licenses and may need licensing for certain cases.

Tips for the best direct PCR or crude sample PCR amplification results:

If direct PCR amplification does not work, reduce the sample input amount, for example use less of bacterial colony material or less of tissue.

  •            For some samples you might need performing a simple lysis with proteinase K, lysozyme or commercially available direct PCR amplification lysis buffers.
  •            Try different dilutions of the lysed sample for the PCR amplification.
  •            Choose primers with high specificity and efficiency for the target sequence to ensure successful amplification.
  •            Use only the hot-start DNA polymerase or master mix for the best amplification result when working with crude samples.
  •            Determine the optimal annealing temperature by conducting a temperature gradient PCR to enhance primer binding and specificity.
  •            Extend the denaturation step to ensure complete DNA denaturation, especially in crude samples with potentially more inhibitors that can be degraded when heating.
  •            Include positive control (known DNA template/primers) and negative controls (no template) to validate the PCR amplification results.

StainIN™ GREEN Nucleic Acid Stain
StainIN™ GREEN Nucleic Acid Stain is a significantly safer alternative to ethidium bromide. It is same easy to use, 4X as sensitive (under Blue LED) and much more secure. More economical as other green dyes, this stain can be also used and disposed with less environmental and health concerns compared to ethidium bromide. It is a fluorescent dye that allows detection of >0,1 ng of DNA in both agarose and polyacrylamide gels. It binds to both dsDNA, ssDNA and RNA and emits green fluorescence when bound to DNA and red fluorescence when bound to RNA detectable under the UV or Blue light and documented with same filters as similar green dyes. StainIN™ GREEN is ideal for DNA extraction from gels for cloning. Smaller than ethidium bromide carcinogenicity has been proved by Ames-test. Mammalian cell mutagenicity tests, both mouse marrow erythrocyte micronucleus and spermatocyte chromosomal aberration tests gave negative mutagenicity results. Carcinogenicity and toxicity of the widely used Ethidium Bromide (EtBr) is one of the biggest safety and environmental problems in the labs where gel electrophoresis is a daily routine. The less toxic nucleic acid dyes address this problem and minimize concerns. The StainIN™ GREEN (SYBR Green-like stains alternative), (SYBR® Green is a registered trade mark of Molecular Probes Inc.) and StainIN™ eco-RED Nucleic Acid Stains by highQu provide a much less-carcinogenic, significantly safer alternative to EtBr while delivering even several times higher detection sensitivity. Same like EtBr, these stains are used during the process of electrophoresis in an agarose gel or PAAG and in the electrophoresis running buffer. Nucleic acid stains are typically divided into two groups – they are either intercalating dyes or minor groove binders. The StainIN™ GREEN and StainIN™ eco-RED Nucleic Acid Stains belong to the group of intercalating dyes that bind to NA and produce the fluorescence signal. Same like many other suppliers of similar products, highQu retains the right to keep the precise chemical information undisclosed and proprietary. The StainIN™ GREEN Nucleic Acid Stain as well as the StainIN™ eco-RED Nucleic Acid Stain are both supplied in water. Detailed safety information is available in MSDS sheets of the stains. Despite proven less mutagenicity, all nucleic acid stains, including SYBR® Green or other shall be handled with care. Used electrophoresis buffer with a stain as well as melted gels shall be run through approved (carbon) filters. If the absence of residual fluorescence is confirmed, the liquids can be disposed with plenty of water down the drain. Alternatively, all used liquids can be autoclaved as the StainIN™ GREEN and StainIN™ eco-RED Nucleic Acid Stains degrade during the long exposure to above 100ºC temperature. The safety office shall be consulted periodically to match local regulations, as they vary and change.

ALLin™ HS Red Taq Mastermix
highQu ALLin™ Hot Start Taq DNA Polymerase is the superior sensitive enzyme. The activity at room temperature is blocked by small molecular inhibitor. Enzyme becomes active only after heating what allows for highly specific and extremely sensitive amplification, no primer dimer formation and no background. In combination with the optimized ALLin™ buffer enzyme provides higher success rates in demanding PCR applications like amplification of crude, complex or longer templates and fast cycling. ALLin™ Hot Start Taq DNA Polymerase has the same PCR accuracy like Taq DNA Polymerase, 4.5 x 10^4 (nucleotides incorporated before the error occurs) and produces A-tailed products suitable for ligating into TA cloning vectors. The convenience of ALLin™ Hot Start Taq DNA Polymerase is maximized by the use of 2X Red colored Mastermix providing the additional advantage of reduced pipetting and minimized errors. The mastermix is even supplied with PCR Water, and the only thing to add is the template with primers. ALLin™ HS Red Taq Mastermix, 2X is premixed with red dye and density reagents for direct loading on the gels after the PCR. In a 2% agarose TAE gel the dye migrates with~350 bp DNA, in 1% agarose TAE gel with ~ 600 bp DNA fragments. ALLin™ HS Red Taq Mastermix, 2X is also a key component in highQu SampleIN™ Direct PCR Kit (DPK0101/5), ensuring outstanding PCR results with crude samples.
