Amplify what others can't.
DeCodi-Fi™ Long&Complex is an All-in-One Mix optimized for the toughest PCR targets: long fragments, ultra-GC-rich regions, and repetitive sequences. Powered by the DeCodi-Fi™ high-fidelity polymerase, it delivers the precision, yield, and consistency that define the DeCodi-Fi™ kit family. Built for long-read sequencing, gene synthesis, and complex genomic assemblies, it enables reliable and accurate amplification even from low-input complex samples where other polymerases fail.
