Product Overview
This rabbit polyclonal antibody recognizes inosine triphosphate pyrophosphatase (gene ITPA) in human, mouse and rat samples and is validated for Western blot, IHC, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 21.4 kDa, and the supplier reports an observed band at about 21 kDa.
Inosine triphosphate pyrophosphatase (ITPA) removes non-canonical purine nucleotides such as ITP, dITP and XTP by converting them to monophosphates. This prevents their incorporation into DNA and RNA. Common ITPA variants reduce enzyme activity and are known to influence the toxicity of thiopurine drugs and ribavirin-associated anemia.
