一般描述
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. Ochratoxin B is dechlorinated analog of ochratoxin B.
应用
Ochratoxin B was used as standard to investigate the degradation of ochratoxin A and B by white rot fungus during solid state fermentation of barley contaminated with ochratoxins. It may be used in displacement immunoassay for detection of ochratoxin A.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.
