- Flexible – ideal for amplifying any target up to 5 kb from DNA extracted from human, animal and plant samples
- Convenient – mastermix facilitates PCR set-up and includes a red dye for improved pipetting ease / accuracy and to enable direct gel loading
- Fast – developed to give sensitive, reproducible and robust amplification of a broader range of targets under fast thermal cycling conditions
MyTaq HS Red Mix is recommended for PCR assays containing complex and low copy number targets as well as multiplex PCR. MyTaq HS Red Mix is comprised of MyTaq HS DNA Polymerase and a novel buffer system that deliver very high yield PCR amplification over a wide range of PCR templates. MyTaq HS has an increased affinity for DNA, enabling reliable amplification from even very low amounts of template. MyTaq HS has been developed to give more robust amplification than other commonly-used polymerases allowing it to perform well with challenging templates and in the presence of PCR inhibitors. Furthermore, the highly efficient nature of MyTaq HS means it gives excellent results under fast PCR conditions. MyTaq HS does not possess polymerase activity during the reaction set-up, thereby reducing the non-specific amplification that can hinder PCR assays from the start.
The product is supplied as a mastermix that requires the addition of only template, primers and water, thereby reducing the number of pipetting steps during PCR set-up, for improved speed, throughput and assay reproducibility. MyTaq Red Mix contains a red dye that increases the visual contrast between the reagent and the reaction vessel for improved convenience and to improve pipetting accuracy. The red dye also enables samples to be loaded directly on to a gel after the PCR without the need to add loading buffer. In addition, MyTaq Red contains dNTPs, MgCl2 and enhancers at optimal concentrations, which helps eliminate the need for optimization, thereby saving time, effort and the cost of performing unnecessary assay repeats.

Application NoteMyTaq™ HS Red Mix
I use the MyTaq HS Red Mix all the time for genotyping purposes. This polymerase is so efficient that my program for 35 cycles finishes just under one hour. The mix is easy to use, and the dye in it allows for direct gel loading after the PCR is finished.

Storage & Stability
All components should be stored at -20°C upon receipt for optimum stability. Repeated freeze/thaw cycles should be avoided.
When stored under the recommended conditions and handled correctly, full activity of the reagents is retained until the expiry date indicated on the outer box label.
On Dry Ice or Blue Ice.
Please Note: We do not recommend the storage of our polymerases at -80 °C as ice crystals could form on the active site, which may affect or destroy the activity of the enzyme.
|No or low PCR yield||Enzyme concentration too low – increase the amount of enzyme in 0.5 U increments.|
|Primers degraded – check quality and age of the primers.|
|Magnesium concentration too low – increase concentration in 0.25 mM increments with a starting concentration of 1.75 mM.|
|Primer concentration not optimized. Titrate primer concentration (0.3-1 µM); ensuring that both primers have the same concentration.|
|Template concentration too low – Increase concentration of template.|
|Perform a positive control to ensure that the enzyme, dNTPs and buffers are not degraded and/or contaminated.|
|Multiple Bands||Primer annealing temperature too low. Increase annealing temperature. Primer annealing should be at least 5°C below the calculated Tm of primers.|
|Prepare master mixes on ice or use a heat-activated polymerase.|
|For problems with low specificity. Try adding 3% DMSO (not supplied) to improve specificity.|
|Smearing or artifacts||Template concentration too high. Prepare serial dilutions of template.|
|Too many cycles. Reduce the cycle number by 3-5 to remove non-specific bands.|
|Enzyme concentration too high - decrease the amount of enzyme in 0.5 U increments.|
|Extension time too long. Reduce extension time in 0.5-1 minute increments.|
