EzPCR™ FAST 2X PCR Master Mix is a ready-to-use premix containing all the components essential for a PCR and agarose gel electrophoresis (DNA polymerase, dNTP, reaction buffer, glycerol, bromophenol blue, and stabilizer). PCR can be performed simply by adding primer pair and template.
As Master Mix is supplied as a 2X concentration format, users should adjust a final reaction to 1X (if final reaction volume is 20 ml, 4 ml of 2X Master Mix should be added). One unit of rTaq Plus DNA Polymerase is contained in 4 ml of 2X Master Mix.
rTaq Plus DNA Polymerase is a thermostable DNA polymerase that designed for a reliable amplification of long and complex targets with a robust yield in an extremely short extension time. Due to its high elongation rate (about 100 bp/sec) and high processivity (about 250 bases), long sized products can be generated within relatively shorter running time compared to any other commercially available enzymes (5 kbp within 60 sec extension).
rTaq Plus DNA Polymerase has no detectable exonuclease activity (5´à3´ or 3´à5´) and generates a 3´dA overhang, suitable for a TA cloning of PCR products.

Standard Experiment Protocol
1. Prepare the 20 ㎕ PCR solution as follows
EzPCR™ FAST 2X Master Mix 10 ㎕
Primer (10 pmol/㎕) each 0.5 ㎕
Template DNA 0.1 - 10 ng
PCR grade distilled water - ㎕
Add distilled water to make 20 ㎕ final volume.
2. Set PCR cycling as follows

* Set 25-35 PCR cycles for effective amplification.
* You can also use two step cycle amplification. (denaturation at 95℃ andannealing / extension at 68℃)
3. You can analyze PCR products by direct loading into agarose gel because PCR Master Mix contains glycerol and bromophenol blue (blue color) essential for a gel loading.
Troubleshooting
1. No products
- Confirmyourtemplateisintact:Try another reaction with a result assured primer pair and templates.
2. Smear bands or smeared background
- Reduce template concentration: High concentration of template can lead to smearing of PCR products. Generally, 1 - 10 ng of plasmid DNA Is working well
- Increase annealing temperature
- Set up a reaction mix on ice
3. Non-specific bands
- Increase annealing temperature
- Consider using PCR additives, like 1-2% DMSO or 0.5 - 1 X Q Buffer
- Confirm specificity of your primers
- Adjust concentration of template
4. Low yield
- Increase PCR cycle number
- Be sure appropriate concentration of your template is added.
