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.
