3.1. Cross-reactivity with wheat lectin The cross-reactivities of Ricin BioThreat Alert® LFDs towards lectins derived from pea, peanut, and wheat, were examined. Neither the pea nor peanut lectin was detected by the LFDs at concentrations as high as 1mg/mL and 250 μg/mL, respectively.
However, the wheat lectin at ≥15 μg/mL purified protein, or as N1000 ppm stone ground wheat, generated false positive responses (see Figs.1 and 2).
