title: Isolation of an inhibitor of DNA synthesis specific for normal and malignant mammary cells.
abstract: A small-molecular-weight inhibitor of DNA synthesis, specific for normal and malignant mammary cells but devoid of species-specificity, has been isolated from bovine mammary glands. This factor has very little effect on RNA metabolism.
