Monoclonal antibodies against human DNA polymerase-alpha do not cross-react with glucocorticoid receptors.
None of 16 independent monoclonal antibodies against human (KB cell) DNA polymerase-alpha recognizes epitopes on cytoplasmic glucocorticoid receptors prepared from the same cells. Consistently negative results are obtained with separate assays that measure antibody binding to uncharged receptors or to charged receptor complexes that have been preloaded with a specific steroid ligand. These results must qualify the interpretation of possible immunological relations between polymerase-alpha and glucocorticoid receptors that were inferred from studies with polyclonal antisera of poorly defined specificity.
