Abstract
A method for reversibly inactivating thermostable DNA polymerase or ligase, which method comprises reacting a mixture of the thermostable DNA polymerase or ligase with a dicarboxylic acid anhydride, wherein the reaction is carried out using a dried DNA polymerase or ligase in an anhydrous aprotic organic solvent, the dicarboxylic acid anhydride being also substantially anhydrous, whereby the reaction results in essentially complete inactivation of enzyme activity.
