Q5U Hot Start High-Fidelity DNA Polymerase is a modified version of Q5 High-Fidelity DNA Polymerase, a novel thermostable DNA polymerase that possesses 3' to 5' exonuclease activity, and is fused to a processivity-enhancing Sso7d domain. Q5U contains a mutation in the uracil-binding pocket that enables the ability to read and amplify templates containing uracil and inosine bases.
