In theory, provided the low cross-reactivity with phallotoxins, a 10-fold dilution of the extract would suffice to dilute the phallotoxins to non-detectable amounts. Nevertheless, antibody-based detection is unique because all of the amatoxins as well as phallotoxins (also those for which logical requirements aren't readily available) bind cumulatively and also present as a single result-- the simple existence or lack of a line. While the LFIA does minimally (0.005%) cross-react with phallotoxins, we can not leave out the possibility that a false positive result for A. A total set of chemical requirements are required to develop a final thought. Hence, the LFIA is a helpful testing tool, which is determining varieties producing cyclopeptides.
