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 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 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.

The HighScriber™ Reverse Transcriptase Mix is a premium tool for the high efficiency reverse transcription of up to 12-15 kb long cDNA. Mix includes HighScriber™ Reverse Transcriptase and Ribonuclease Inhibitor for save, robust cDNA synthesis and ease of use. HighScriber™ Reverse Transcriptase allows for high detection sensitivity from 1 pg of total RNA. The wide reaction temperature range (38°C - 55°C) ensures efficient cDNA synthesis from complex or GC rich templates. The enzyme uses ssRNA or ssDNA as a template, possesses no detectable Ribonuclease H activity specific to RNA in RNA-DNA hybrids. A highly reduced Ribonuclease H activity allows for transcription of full lengths long transcripts. HighScriber™ Reverse Transcriptase can be used for RACE as it has terminal transferase activity - adds cytosines to 3’ ends of cDNA. The Ribonuclease inhibitor premixed with the RT ensures RNA protection from ribonuclease degradation. Supplied 5X ALLin™ HighScriber Buffer includes everything you need for the cDNA synthesis reaction. To minimize pipetting steps it contains MgCl2, dNTPs, enhancers, stabilizers. The only things to add is the template RNA and primer.

highQu ready to use DNA ladders are mixtures of highly purified plasmid digests and PCR products. The high ladder purity allows for exceptional stability and room temperature storage. Ladders are ready to be directly loaded on agarose gels and are supplied with the loading dye solution for probe DNA. They provide sharp bands for DNA sizing and allow for approximate DNA quantification by comparing the amount of DNA of the band similar in size to your sample band. Proper agarose gel preparation is a crucial step in DNA electrophoresis. Here are some detailed tips to ensure optimal separation and visualization of DNA fragments: Proper agarose gel preparation is a crucial step in DNA electrophoresis. Here are some detailed tips to ensure optimal separation and visualization of DNA fragments: Gel casting: Choose the appropriate agarose concentration based on the expected fragment size range. Measure the required amount of agarose and add it to the appropriate volume of buffer. Heat the mixture in a microwave until the agarose is completely dissolved. Allow the mixture to cool to a temperature that is safe to touch but still liquid before pouring it into the gel tray. Avoid creating air bubbles during pouring by slowly and gently filling the gel tray. Wait till the agarose gel is completely formed. Immerse the gel into the tray with the buffer, remove the combs and ensure the gel is completely covered by electrophoresis buffer. DNA sample loading: Prepare DNA samples by mixing them with loading buffer supplied with the DNA ladder. This buffer helps the samples sink into the wells and provides tracking dyes for visualization. Load a suitable volume of each DNA sample into the wells. Use DNA ladder or molecular weight marker on both sides of the sample or gel for reference. highQu DNA ladders are ready to use and do not require any extra preparation for loading. Mix the ladder and the sample well before loading on the gel. Electrophoresis running conditions: Set the desired voltage according to the fragment size and the resolution required. Lower voltages are suitable for resolving larger fragments. Start the electrophoresis run and monitor the migration of tracking dyes. Stop the run once the desired separation is achieved, but be cautious not to allow the DNA bands to run off the gel. Stain the gel post electrophoresis according to the conditions described by Nucleic Acid Stain supplier, for example use highQu StainIN™ GREEN NA 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.
