The test is based on mouse monoclonal antibodies against OTA. With this kit 10 analyses can be performed. The kit contains all the reagents required to perform the tests. The cut-off value of this test is 3 µg/kg of OTA in roasted coffee.

Ochratoxin A (OTA) is a nephrotoxic and hepatocarcinogenic mycotoxin produced by Penicillium verrucosum and Penicillium viridicatum in temperate and cold climates and by a number of Aspergillus species such as A. ochraceus in warmer and tropical areas of the world.
