Anti-TK (Ab-13) Antibody

Thymidine kinase (TK) is a key enzyme in the nucleoside salvage pathway and is widely investigated in studies of DNA synthesis, cell proliferation, and tumor biology. This unconjugated rabbit polyclonal reagent from Antibodies.com is raised against TK and validated for western blot, immunohistochemistry, and immunofluorescence workflows on human samples. Supplied as 100 µl of polyclonal antiserum, it supports detection of endogenous TK expression in cultured cells and paraffin-embedded tissue sections.

Researchers in oncology, antiviral drug screening, and suicide gene therapy development rely on anti-TK antibodies to monitor proliferative activity and transgene expression. The unconjugated format allows flexible pairing with enzyme- or fluorophore-labeled secondary reagents for chromogenic or fluorescence-based readouts in research use only applications. The polyclonal host response provides recognition of multiple epitopes on the target, an advantage when probing native protein in fixed tissue preparations and resolving isoform-level differences that monoclonal reagents can miss.
