Description

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.

Application

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”.
