EPICENTRE’s MasterAmp™ Tfl DNA Polymerase is a recombinant DNA polymerase with good thermostability (to ~95°C) and processivity (15 kb PCR products reported). This enzyme is of very high purity and free of detectable nonspecific DNA exo- and endonuclease and RNase activities. Its specific activity has been functionally tested in PCR. The presence of betaine in the MasterAmp 10X PCR Enhancer supplied in the kit substantially improves the yield and specificity of amplification of many target sequences, especially those containing a high G+C content or secondary structure. It also greatly improves the yield consistency of PCR products in multiplex PCR reactions.
