Radioimmunoassay is an established method to determine the amount of a specific substance in a given cell or tissue sample. Commercially available RIA or Elisa are very cost intensive. Here, we describe the generation of radioactive cGMP tracer and the quantification of cGMP. Although working with radioactive material requires experience and care, this method is very sensitive and rather cheap, once it is established.
