A novel "eukaryote-made" thermostable DNA polymerase which is free from bacterial DNA contamination.

To achieve the production of thermostable DNA polymerase free from bacterial DNA contamination, we developed "eukaryote-made" thermostable DNA (Taq) polymerase. The novel "eukaryote-made" thermostable DNA polymerase resolves the problem of contaminating bacterial DNA in conventional "bacteria-made" thermostable DNA polymerase as a result of its manufacture and incomplete purification. Using "eukaryote-made" thermostable DNA polymerase, the sensitive and reliable detection of bacteria becomes feasible for large fields, thereby making the development of a wide range of powerful applications possible.
