Application

Ochratoxin A−BSA conjugate from Aspergillus ochraceus has been used in carbonate-bicarbonate buffer to coat the high-affinity 96-well polystyrene plates for indirect competitive enzyme-linked immunosorbent assay. It has also been used as a standard in the determination of ochratoxin A in serum by capillary electrophoresis with laser-induced fluorescence detection (CE-LIF).

Biochem/physiol Actions

Ochratoxin A (OTA) is a mycotoxin that is the most toxic among the other ochratoxins. It is produced by Aspergillus carbonarius, A. ochraceus, and Penicillium verrucosum. OTA acts as a major food contaminant and is considered nephrotoxic, teratogenic, neurotoxic, hepatotoxic, and immunotoxic. OTA is known to elevate oxidative stress at a cellular level.
