Product Overview
Clone AOBB-20 is a rabbit monoclonal antibody that recognizes thymidine kinase, cytosolic (gene TK1) in human samples and is validated for Western blot, IHC, ICC/IF, immunoprecipitation and flow cytometry. The predicted molecular weight is 25.5 kDa, and the supplier reports an observed band at about 25 kDa.
Thymidine kinase 1 (TK1) is a cytosolic enzyme of the nucleotide salvage pathway that phosphorylates thymidine to thymidine monophosphate for DNA synthesis. Its expression rises sharply in S phase and it is degraded after mitosis, so its levels track cell proliferation. TK1 is studied as a proliferation marker and in nucleotide metabolism.

Samples with a confirmed band (WB): human A431 cells, human U2OS cells, human PC-3 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 30 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 1:5000 overnight at 4 °C, HRP-conjugated secondary antibody at 1:500, ECL detection.
Immunogen
Synthetic peptide based on the sequence of human thymidine Kinase 1.
Reactivity Notes
The supplier lists reactivity with human. UniProt places thymidine kinase, cytosolic in the cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
