Analytical and bioanalytical chemistry, 400(8), 2615-2622 (2011-04-05)
The paper presents a new sample clean-up method based on immuno-ultrafiltration for the analysis of ochratoxin A in cereals. In contrast to immunoaffinity chromatography, in immuno-ultrafiltration, the antibodies are used in non-immobilised form. Ochratoxin A was extracted with ACN/water (60/40

Journal of chromatography. A, 864(1), 89-101 (2000-01-12)
A new and accurate method to quantify ochratoxin A (OA) in table wine has been developed. The method uses commercial immunoaffinity columns for clean-up and high-performance liquid chromatography (HPLC) with fluorescence detection for quantification of the toxin. Wine was diluted
Wei Ma et al.
Biosensors & bioelectronics, 42, 545-549 (2012-12-25)
A simple and ultrasensitive method was developed for the detection of Ochratoxin A, utilizing an aptamer as a molecular recognition probe and real-time quantitative PCR (RT-qPCR) amplification of its complementary DNA as signal generators. Under the optimized conditions, the cycle
