Aflatoxin M1, B1 (AFM1, AFB1)

May be stored at 4 °C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20 °C. Aliquots are stable for at least 12 months at -20 °C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.

Reactive to Aflatoxin M1 (AFM1) and Aflatoxin B1 (AFB1), but not reactive to BSA and other irrelevant antigens by ELISA. Similarly, a competitive binding assay using AFM1 as binding competitor to compete with AFM1-BSA-125I showed that AFM1 can effectively inhibit the binding of the above 4 monoclonals to AFM1-BSA-125I and the inhibition degree corresponded to the amounts of AFM1 used.
