MangoMix™ is a convenient, ready-to-go, 2x Reaction Mix containing MangoTaq™ DNA Polymerase, MgCl2 and ultra-pure dNTPs manufactured by Bioline. The Mix is optimized and ready-to-use and requires only the addition of water, template and primers.
MangoMix™ is optimized and ready-to-use, so the user need only add water, template and primers. MangoMix reduces the time required to set up reactions, thereby minimizing contamination risks and providing greater reproducibility through a reduction in the number of pipetting steps. MangoMix can be loaded directly onto an agarose gel for analysis, without the need for a separate gel-loading buffer.
The presence of dyes has no effect on routine enzymatic manipulations, although rare exceptions may exist. MangoMix has been optimized for a wide variety of templates. An additional 50 mM of MgCl2 solution is included should any fine adjustments be required.

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.
Bioline's mixes contain magnesium chloride at the following concentrations (please see table below). An additional tube of 50 mM MgCl2 solution is supplied with each mix to facilitate further optimization if required.
| Bioline Mix | Final Magnesium Concentration |
| ACCUZYME Mix | 2.0 mM. |
| BioMix / BioMix Red | 2.5 mM. |
| ImmoMix / ImmoMix Red | 3.0 mM. |
| BIO-X-ACT Short Mix | 2.0 mM. |
| MangoMix | 2.5 mM. |
| MyTaq | 3.0 mM. |
| RANGER | 1.5 mM. |
| Observation | Recommended Solution(s) |
| 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. |
