Pickering - Immunoaffinity & Spe Sample Clean-Up Columns

Aflatoxins and Ochratoxin A are produced by fungi, e.g. Aspergillus and Penicillium species. Therefore both toxin types are found together in many foods and animal feeds, e.g. cereals. Deoxynivalenol, also known as Vomitoxin, is a metabolite of various molds of the genus Fusarium (F. colmorum, F. graminearum) and can often be found together with other mycotoxins. Of significant assistance is the clean-up of extracts by a combined immunoaffinity column (the Afla-OtaCLEAN column) for both Aflatoxins and Ochratoxin A in one step. The subsequent analysis may then be performed by HPLC with postcolumn derivatization or other techniques.
