5. Conclusion
Cosmetics suspected of containing ricin can be analyzed using the BioThreat Alert® LFDs provided the samples are sufficiently diluted to prevent flow problems. It is recommended
that 50% PBSTM be used with immunoassays whenever samples are suspected of containing wheat lectin. In the event that a cosmetic product generates a positive response with an LFD, the sample should be reanalyzed using 50% PBSTM as the analytical buffer and whenever possible also confirmed using a second, independent method.
