I am performing High-fidelity general PCR using Takara PrimeSTAR™ HS DNA Polymerase , but there is no amplification and very dense bands of primer dimers are visible. the cDNA is of superior quality and the dNTPs, buffer and Taq seems good too. The amplification of same template using i-StarMAX™ GH DNA Polymerase is good but not with the Takara PrimeSTAR™ HS DNA Polymerase. It would be kind enough of you to suggest some solution, here I'm attaching picture of my results.
