Application Notes Aug 29, 2008
In preliminary studies to characterize the KOD1 DNA polymerase, researchers found that the enzyme had fidelity comparable to Pfu DNA polymerase, but with an extension rate (referred to as speed) 5 tim 00004000 es higher and processivity 10 to 15 times higher than the Pfu enzyme (Takagi 1997). When amplifying DNA for cloning, high fidelity DNA polymerases, such as KOD polymerase, are recommended. (Nature News Service)

Invitrogen will obtain a license from Agilent and pay an undisclosed royalty to sell its DNA polymerase blend products. The company said it expects the benefit in the fourth quarter of 2008 from legal settlements to be $8 million. (San Diego Union-Tribune -- Business)
Adaptive expression responses in the Pol-gamma null strain of S. pombe depleted of mitochondrial genome Sep 15, 2007
DNA polymerase gamma (Pol-gamma) has been shown to be essential for maintenance of the mitochondrial genome (mtDNA) in the petite-positive budding yeast Saccharomyces cerevisiae. Budding yeast cells lacking mitochondria exhibit a slow-growing or petite-colony phenotype. (BioMed Central)
