EzPCR™ HS 2x Master Mix
EBT-7821 / EBT-7821-5
CAT #EBT-7821 / #EBT-7821-5
QTY

Description 
EzPCR™ HS 2X PCR master mix includes all components required for PCR except DNA template and primers. This pre-mixed formulation saves time and reduce contamination. Also, an addition of gel loading buffer is no needed.
   HS Polymerase is a mixture of PCR enzyme derived from rTaq DNA polymerase and monoclonal antibody to Taq DNA polymerase. The antibody inhibits the polymerase activity and prevent non-specific amplification derived from misprinting of primer dimer before PCR cycling. The antibody is denatured during the initial denaturation step, allowing this product to be used with standard PCR. This product provides convenience PCR that enhances the specificity and sensitivity.
   rTaq DNA polymerase that is a recombinant thermostable DNA polymerase from Thermus aquaticus has a 5’ à 3’ exonuclease activity and generates a 3’dA overhang.
  
Applications
  HOT-start PCR, RT-PCR, genotyping, SNP PCR, multiplex PCR. 

Qualifying Test
  Activity, SDS-PAGE purity, performance tests, genomic DNA contamination test, confirmation test for the absence of endo and exonucleases.
 
Storage Condition
  Store at -20 ℃.
  EzPCR™ HS 2x PCR Master Mix is stable for at least 1years at recommended storage condition. 

Features
- 5’ → 3’ exonuclease : yes
- 3’ → 5’ exonuclease : no
- strand displacement : no
 
Standard Experiment Protocol
1. Prepare 20㎕ PCR solution as follows
 
PCR grade distilled water                           -  ㎕                        
EzPCR™ HS 2x PCR Master Mix              10 ㎕
Primer (10 pmol/㎕)                         each 0.5 ㎕     
Template                                             1 – 50 ng    
                                                                                      
Adjust final vol. to 20 ㎕ with PCR grade distilled water.
 
2. Set PCR cycling as follows

Trouble-shooting Guide
1. No products
- Confirm your template is intact : 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 and
    10-100 ng of genomic DNA are 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
 
4. Low yield
- Increase PCR cycle number
- Be sure appropriate concentration of your template is added.
