One-Step tHDA (thermostable HDA)
- Set up a 50 μl reaction in a 0.2 ml or a 0.5 ml micro centrifuge tube in a sterile hood or a PCR Workstation.
H2O X μl 10X Annealing buffer II 5 μl MgSO4 (100 mM)* 2 μl NaCl (500 mM)* 4 μl IsoAmp® dNTP Solution 3.5 μl DNA template X μl Forward Primer (5 μM)* 0.75 μl Reverse Primer (5 μM)* 0.75 μl IsoAmp® Enzyme Mix 3.5 μl Total volume 50 μl
- Mix the reaction by brief vortexing or by pipetting followed by brief centrifugation. Overlay the reaction mixture with 50 μl mineral oil. Place the tubes on ice.
- Incubate at 65ºC for 90 minutes using a thermocycler, a water bath or an incubator.
- Load 10 μl of the tHDA product on a 2% agarose gel.
* The condition of tHDA reactions can be further optimized by titering the following components:
Components Recommended concentration Recommended concentration for titering MgSO4 3.5 to 4 mM 3 to 4.5 mM NaCl 30 to 40 mM 20 to 50 mM Primer 75 to 100 nM 50 to 200 nM
