KAPA HiFi Uracil+ DNA Polymerase is a modified version of KAPA HiFi DNA Polymerase that is engineered to tolerate uracil residues in bisulfite-treated DNA. Bisulfite treatment of DNA results in the conversion of unmethylated cytosine residues into uracil, while the methylated residues are left unmodified. Enzymes used for library amplification in bisulfite-sequencing workflows must be able to read through uracil residues and tolerate low concentrations of AT-rich DNA. Traditional high-fidelity DNA polymerases are typically not suitable for this type of application as the enzymes stall when a uracil is encountered. KAPA HiFi Uracil+ DNA Polymerase has been developed to read through uracil residues while still retaining the performance benefits of HiFi DNA Polymerase, such as high yields, low-bias, and uniform sequencing coverage.
