We offer comprehensive support to develop pharmaceutical products for pharmaceutical companies using our advanced technological capabilities.




Conduct the pharmacokinetics, pharmacology, properties and safety studies of a drug in the early stage of drug development.


Synthesize compounds labeled with radioisotopes (RIs) or stable isotopes (SIs).


Conduct pharmacokinetic studies using test animals, cells or enzymes in compliance with reliability standards.


Perform radio receptor assay (RRA),inhibition assay, functional assay, immunoassay and cell base assay using enzymes or cells in compliance with the GLP Standard.


Measure toxicokinetics, biomarkers and neutralizing antibodies in compliance with the GLP Standard.


Measure drug concentrations of biologic samples or biomarkers and examine gene polymorphism in clinical studies in compliance with the GLP Standard.

- Our main business is pharmacokinetic tests with our custom-ordered synthesis of radiolabeled compounds. We develop and implement new tests adapted to scientific development and updated regulations.

- The Pharmacokinetics Laboratory started operations in 1965 in Tokai-mura, Ibaraki Prefecture, Japan for the purpose of contributing to the advance and development of scientific research through the radioisotope business. The laboratory conducts tests adapted to the times.

- We support rational and effective development of your pharmaceutical products. Test processes are summarized.
