ImmoMix™ is a complete ready-to-use high yield heat-activated 2x reaction-mix, which simply requires the user to add water, template and primers, and then pre-heat to 95°C for 10 minutes to carry out successful PCR assays.
ImmoMix™ is a complete ready-to-use high yield (fig. 1), heat-activated 2x reaction-mix, which simply requires the user to add water, template and primers, and then pre-heat to 95°C for 10 minutes to successfully carry out PCR assays. The 10 minute activation step eliminates the presence of non-specifics such as primer-dimers and mis-primed products, since the enzyme is inactive at initial low temperatures.
ImmoMix is based on IMMOLASE™ DNA Polymerase, which leaves an ´A´ overhang, and has been optimized for a wide variety of templates. Additional MgCl2 solution is included should any fine adjustments be required.
ImmoMix reduces the time needed to set up reactions, thereby reducing the risk of contamination. Greater reproducibility is ensured by reducing the number of pipetting steps that can lead to pipetting errors.

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 on the outer box label.
Components may also be stored at +4°C if required, although storage at -20°C is recommended. When stored at +4°C, reagents will remain stable for a period of two weeks from date of receipt.
On Dry Ice or Blue Ice.
Certificates of Analysis for ImmoMix™ are grouped by catalogue number and then listed by batch number. Larger pack sizes are listed first. To locate the COA for your product, first find the catalogue number and then the required batch number.
|No or low PCR yield||For difficult templates (AT and GC rich).|
|Enzyme concentration too low – increase the amount enzyme in 0.5U increments.|
|Magnesium concentration too low – increase concentration in 0.25mM increments with a starting concentration of 1.75mM.|
|Primer concentration not optimised. Titrate primer concentration (0.3-1µM); 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 Hi-Spec Additive or 2x PolyMate (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 0.5U increments.|
|Extension time too long. Reduce extension time in 0.5-1 minute increments.|
