Product information "CozyXL™ Prestained Protein Ladder"
highQu ready to use Prestained Protein Ladders are mixtures of highly recombinant proteins with coupled chromophores providing sharp protein bands and bright colors on denaturing polyacrylamide gels. The high ladder purity allows for exceptional stability and room short term temperature storage. Ladders are ready to be directly loaded on gels without any preparation or heating. They provide sharp bands for approximate protein sizing and allow for monitoring of electrophoresis process and Western transfer efficiency.
Our improved 2X 1Step RT qPCR Probe Kits provide highly sensitive target RNA detection when working with a wide variety of samples. The optimized 1Step RT qPCR Pro Mix in combination with a blend of thermostable Reverse Transcriptase and an advanced RNase Inhibitor (RT-Pro Mix) allows for a single step, one tube RT qPCR with great results even in multiplex reactions.
The novel RT-Pro Mix ensures safe and efficient RNA template conversion into a single-stranded cDNA. Pure RNA samples, as well as lysed crude samples can serve as templates for one-step RT qPCR. Though the kit was not specifically designed for crude sample qPCR, it has a potential to work well for this application.
The robust 1Step RT qPCR Pro Mix is a 2X concentrated qPCR master mix which includes dNTPs, buffer, and the hot start Taq DNA Polymerase. The Hot Start function ensures the highest sensitivity and specificity under both standard and fast qPCR cycling conditions.
The kits provide excellent results on both AT and GC-rich templates and show early Ct values with minimum or no optimization.
Our kits include PCR Water to guaranty the best performance. To suit the broad instrument range the 2X 1Step RT qPCR Probe Kits are available in three versions – without ROX, with low or high ROX concentration.
highQu ALLin™ Taq DNA Polymerase is the versatile engineered enzyme which in combination with the optimized ALLin™ buffer provides higher success rates in demanding PCR applications like amplification of complex templates, crude sample PCR and fast cycling. ALLin™ Taq DNA Polymerase has the same PCR accuracy like Taq DNA Polymerase, 4.5 x 10^4 (a number of correct nucleotides incorporated before the error occurs) and produces A-tailed products suitable for ligating into TA cloning vectors.
The convenience of ALLin™ Taq DNA Polymerase is maximized by the use of 2X Red Mastermix providing the additional advantage of reduced pipetting and minimized errors.
ALLin™ 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.
The mastermix is even supplied with the PCR Water, and the only thing to add is the template with primers.
highQu dNTP sets and mixes meet all highest industry standards and allow for unrivaled performance of your PCR and other DNA synthesis, labeling or sequencing reactions.
Produced under the stringent quality monitoring conditions, they guaranty reproducible results. More than 99% HPLC purity eliminates inhibitions of PCR and allows for increased yields with higher dNTP concentrations.
Exceptional stability of dNTPs allows for short term ambient temperature shipments, short term room temperature storage or long PCR of more than 30 kb targets, as well as long amplifications exceeding 40 cycles.
highQu Taq DNA Polymerase is the classical enzyme for routine PCR applications providing high amplification yields of 3-5 kb targets under various conditions. Taq DNA Polymerase is purified from a recombinant E. coli strain carrying the Taq DNA polymerase gene.
Taq DNA polymerase is thermostable 5´ → 3´ DNA polymerase. It lacks 3´ → 5´ exonuclease (proofreading) activity and has low 5´ → 3´ exonuclease activity. Polymerase exhibits deoxynucleotidyl transferase activity resulting in A-overhang at the 3'-ends of PCR products and allowing for TA cloning. The PCR accuracy of Taq DNA Polymerase is 4.5 x 104 (a number of incorporated nucleotides before the first error occurs).
The supplied reaction buffer for most flexibility in optimization, contains no dNTPs and no magnesium. The 50 mM MgCl2 solution is provided separately what allows for magnesium optimization starting from 1 mM up to 4 mM final concentration upon the need. The dNTPs in sets or mixes can be purchased from highQu separately.
The most widely used PCR enzyme is the DNA polymerase from Thermus aquaticus. Taq DNA polymerase amplifies template DNA by adding nucleotides to the 3' end of a DNA strand in a template-dependent manner where short single-stranded primers that anneal to the template provide a starting point for polymerization.
The enzyme has a 5' - 3' polymerase activity and lacks 3' - 5' exonuclease or so-called proofreading activity. For optimal performance, Taq DNA polymerase requires not only template DNA and reverse and forward primers, but also such essential PCR reaction components as deoxyribonucleotide triphosphates (dNTPs), and magnesium chloride. Optimized buffers commonly supplied with commercial Taq Polymerase enzymes contain certain salt concentration and have balanced pH value.
Taq DNA polymerase has several other advantageous properties over other enzymes used for the PCR. It is known for a high stability and resistance to PCR inhibitors. The inhibitor resistance allows performing direct PCR reactions from crude non-purified templates, such as colony PCR. At highQu, Taq DNA Polymerase is either available as a stand-alone enzyme supplied with a ALLin™ Buffer, or as a convenient 2X concentrated master mix formulation.
