Abstract
Previous research has shown that thymidine kinase 1 (TK1), a nucleotide salvage pathway enzyme, is an accurate prognostic and diagnostic tumor marker. However, the current radioisotope assay for TK1 is cumbersome and has hampered the clinical application of this diagnostic technique in cancer management. To overcome the problems of the current radioisotope assay, we have produced monoclonal antibodies (MAbs) using purified TK1 from Raji cell extract. Production and confirmation of their specificity was confirmed using Western blot, immunohistochemical staining, TK1 activity inhibition assays, and enzyme-linked immunoadsorbent assay (ELISA) techniques. Thus, in the future, these antibodies may aid in the early detection of cancer and more accurate prognosis, as well as allowing for an increased ability to study the function of TK1 in basic cellular processes.
