Abstract Storage of immunosensors has been rarely studied despite its importance for technology transfer to diagnostic companies. In this study was proposed a novel stabilizer storage solution of an electrochemical immunosensor for the detection of Salmonella. A commercial stabilizer solution for immunoglobulin was also tested for the devices. The immunosensors were kept in solution for 15, 30, 60, 90 and 120 days at refrigerated (4 ºC) and room temperature (25 ºC). There was a statistical difference (p < 0.05) between the two stabilizer solutions and the temperatures. The best condition found for the storage of the immunosensors was the formulated solution under refrigeration (4 ºC).
