General description

Certan Vial
Ochratoxin is a mycotoxin, produced by genus Aspergillus and Penicillium. Ochratoxin producers are widely distributed in foods such as cereals. Ochratoxins are isocoumarin derivatives. A quantitative detection method for ochratoxin A by using aptamer (single-stranded oligonucleotides selected in vitro to bind to molecular targets) is reported.


Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
Ochratoxin A (OTA) was used in quantification of OTA in table wine by immunoaffinity column clean-up and high-performance liquid chromatography. It was used as analytical standard in sample clean-up method based on immuno-ultrafiltration for the analysis of OTA in cereals. It was used as analytical standard to study the influence of OTA on the rat embryonic neural cells cultured in high density “micromass cultures”.

Embryonic midbrain micromass cultures were exposed for five days to ochratoxin A (OTA) at seven concentrations (ranging from 0.16 to 10 microg/mL). Cell viability was assessed in neutral red uptake test (NRU), and differentiation - by immunoenzymatic determination of structural...

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...

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...

By taking advantage of the intrinsic fluorescence of ochratoxin A (OTA), we present a fluorescence anisotropy approach for rapid analysis of the interactions between OTA and aptamers. The specific binding of OTA with a 36-mer aptamer can induce increased fluorescence...
