General description

Diethylenetriaminepentaacetic acid is a diethylenetriaminepentaacetic anhydride, which is a bifunctional chelating agent. It is used for the treatment of poisoning.

Application

Diethylenetriaminepentaacetic acid has been used:
  • for cofilin activity assay
  • to determine the specificity of superoxide in the transverse aortic constriction (TAC) hearts
  • for Europium bead-based detection assays
  • to detect reduced (S- active) or irreversibly oxidized (SO3H inactive) tyrosine-protein phosphatase non-receptor type 6 (SHP-1) in thymocytes
