Ralf Blank et al.
The Journal of nutrition, 134(9), 2355-2358 (2004-08-31)
The mycotoxin ochratoxin A (OA) is a cause of endemic nephropathy in farm animals and humans. Reabsorption of OA along the nephron results from nonionic diffusion and by carrier-mediated mechanisms, indicating that urine alkalinization may help to accelerate OA excretion
Vasilica Lates et al.
Analytical and bioanalytical chemistry, 402(9), 2861-2870 (2012-02-15)
We report here the development of a new assay for the detection of ochratoxin A (OTA) based on the use of its dechlorinated analogue, ochratoxin B (OTB), in a displacement immunoassay. OTB was immobilised on controlled-pore glass beads followed by

Journal of chromatography. A, 1217(52), 8249-8256 (2010-11-30)
A validated high-performance liquid chromatography (HPLC) method with fluorescence detection for the simultaneous quantification of ochratoxin A (OTA) and its analogues (ochratoxin B (OTB), ochratoxin C (OTC) and methyl ochratoxin A (MeOTA)) in red wine at trace levels is described.

Food additives and contaminants, 18(8), 730-738 (2001-07-27)
Blood serum, kidney, liver and muscle sample per animal were collected from slaughtered pigs (n = 52). The samples were analysed for ochratoxin A (OTA) and B (OTB) by HPLC methods. Zearalenone (ZEA) in serum was analysed by enzyme immunoassay.
J P Harris et al.
Phytochemistry, 58(5), 709-716 (2001-10-24)
Shaken liquid fermentation of an isolate of Aspergillus ochraceus showed growth-associated production of ochratoxins A and B, followed by production of a related polyketide diaporthin. Later, between 150 and 250 h, mellein accumulated transitorily. In contrast, shaken solid substrate (shredded
