Abstract
Antibodies which are specific to a thermostable DNA polymerase can be used to reduce or eliminate the formation of non-specific products in polymerase chain reaction methods. These antibodies and other temperature sensitive inhibitors are effective to inhibit DNA polymerase enzymatic activity at a certain temperature T.sub.1 which is generally below about 85.degree. C. The inhibitors are irreversibly inactivated at temperature T.sub.2 which is generally above about 40.degree. C. T.sub.2 is also greater than T.sub.1. Such inhibitors can be supplied individually or in admixture with the DNA polymerase in a diagnostic test kit suitable for PCR.
