  • Title: Direct enzyme-linked immunosorbent assay for determining aflatoxin M1 at picogram levels in dairy products.
    Author: Fremy JM, Chu FS.
    Journal: J Assoc Off Anal Chem; 1984; 67(6):1098-101. PubMed ID: 6440890.
    Abstract:
    Protocols for detecting picogram quantities of aflatoxin M1 in dairy products were established. Milk samples were subjected to a reverse phase Sep-Pak C18 cartridge treatment before analysis by an enzyme-linked immunosorbent assay (ELISA) according to previously published procedures. M1 in yogurt, brick cheddar, and ripened Brie cheese was extracted by a modified Pons method, subjected to a normal phase silica cartridge treatment, and analyzed by ELISA. The detection limits for M1 in milk, yogurt, cheddar, and Brie were 10, 10, 50, and 25 ppt (ng/kg), respectively. Recovery for M1 added to these products was in the range 70-110%. Good agreement was found for M1 levels in several naturally contaminated milk samples analyzed by both ELISA and liquid chromatography.
