Scientific Data Images for Human Thymidine Kinase 1 Antibody

Detection of Human Thymidine Kinase 1 by Western Blot.

Western blot shows lysates of HeLa human cervical epithelial carcinoma cell line. PVDF membrane was probed with 1 µg/mL of Rabbit Anti-Human Thymidine Kinase 1 Monoclonal Antibody (Catalog # MAB81801) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (HAF008). A specific band was detected for Thymidine Kinase 1 at approximately 25 kDa (as indicated). This experiment was conducted under reducing conditions and using Western Blot Buffer Group 1.

Detection of Human Thymidine Kinase 1 by Simple WesternTM.

Simple Western lane view shows lysates of A431 human epithelial carcinoma cell line, HeLa human cervical epithelial carcinoma cell line and SK-BR-3 human breast cancer cell line, loaded at 0.2 mg/mL. A specific band was detected for Thymidine Kinase 1 at approximately 32 kDa (as indicated) using 10 µg/mL of Rabbit Anti-Human Thymidine Kinase 1 Monoclonal Antibody (Catalog # MAB81801) . This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Background: Thymidine Kinase 1

Thymidine kinases are 2'-deoxythymidine kinases that phosphorylate deoxythymidine and generate deoxythymidine 5’-phosphate (1). Thymidine kinases have a key function in the synthesis of DNA and thereby in cell division, as they are part of the unique reaction chain to introduce deoxythymidine into the DNA. Two forms of thymidine kinase are present in mammalian cells, TK1 and TK2. TK1 is cell cycle-dependent and is present in the cytoplasm only in anticipation of cell division (2, 3); whereas TK2 is located in mitochondria and is cell cycle-independent (4). TK1 is synthesized by the cell during the S phase of cell division and is degraded after cell division is completed (5). TK1 normally occurs in tissue as a dimer and can be converted to more active tetrameric form by ATP binding (6). TK1 is feedback inhibited by thymidine triphosphate, the product of the further phosphorylation of thymidine (7). Because tumor cells replicate much more frequently than normal cells and requires faster DNA synthesis and higher TK1 activity, TK1 is a cancer maker especially for hematologic malignancies (8, 9). In clinical chemistry TK1 is used as a proliferation marker in the diagnosis, control of treatment and follow-up of malignant disease (10). In addition, thymidine kinase is required for the action of many antiviral drugs (11). The enzymatic activity of recombinant human TK1 is measured using a phosphatase-coupled method (12).
