EVO HS Super-Fidelity DNA Polymerase: The Ultimate High-Fidelity Enzyme for Precise PCR

EVO HS Super-Fidelity DNA Polymerase is a specialized thermostable enzyme engineered to deliver ultra-high fidelity, hot-start PCR, and blunt-end product formation. It is a preferred polymerase for precision molecular cloning, Next-Generation Sequencing (NGS) workflows, diagnostic assay development, and mutagenesis experiments.

This in-depth guide examines its biochemical properties, reaction conditions, applications, comparison with other enzymes, and real-world use cases.

What Makes EVO HS Polymerase Different?

Unlike conventional Taq DNA polymerase, EVO HS features a hot-start mechanism combined with 3’ to 5’ exonuclease proofreading activity. This allows for:

• Ultra-high accuracy for mutation-free amplification

• Low background amplification thanks to hot-start control

• Blunt-end PCR products, suitable for direct blunt-end ligation
