Purified herpes simplex virus thymidine kinase has been used to immunize mice for the production of monoclonal antibodies to the enzyme. Monoclonal antibodies were successfully produced against both herpes simplex virus type 1 and type 2 enzymes. These antibodies should prove useful for detecting the enzyme under a variety of experimental conditions. We also demonstrate that the antibodies can ...

Human deoxyribonucleoside kinases are required for the pharmacological activity of several clinically important anticancer and antiviral nucleoside analogs. Human deoxycytidine kinase and thymidine kinase 1 are described as cytosolic enzymes in the literature, whereas human deoxyguanosine kinase and thymidine kinase 2 are believed to be located in the mitochondria. We expressed the four human d...

Malignant cells have enhanced sensitivity to inhibition of growth by thymidine. Cell growth of the permanent lymphoid cell line CCRF-CEM, originating from a patient with acute lymphoblastic leukemia, is inhibited by 3 x 10(-5) M thymidine, compared to 1 to 5 x 10(-3) M thymidine required to inhibit growth of normal lymphoid lines. Thymidine-resistant cells were isolated at a frequency of approx...
