I-5 Hi-Fi DNA HotStart Polymerase is an ultra-fast and high-fidelity DNA polymerase. It provides robust amplification of difficult templates including plasmids, BACS, genomic DNA, and lambda DNA. It allows the amplification of up to 8kb human genomic DNA and up to 21kb lambda DNA. It has an extension speed of 1 kb / 10-15 seconds depending on template type. This allows users to save time by speeding up PCR reactions and provides higher fidelity than Taq or Pfu. The enzyme contains a HotStart mechanism that inactivates the enzyme until it is heated. This allows users to setup PCR reactions at room temperature without worrying about primer dimers or non-specific preamplification.
Feature
• Fast – 4X faster than hot start Taq
• Robust – high inhibitor tolerance
• High yields – high efficiency
• Long PCR products
