A case of acute, severe allergic conjunctivitis is reported in a biochemist who had been grinding Bandeiraea simplicifolia, the source of an anti-B lectin. A crude extract of these beans produced immediate-type skin test reactivity, and reaginic antibodies were demonstrated in her serum. Several
Sambucus species contain a number of lectins with and without antiribosomal activity. Here, we show that dwarf elder (Sambucus ebulus L.) blossoms express two D-galactose-binding lectins that were isolated and purified by affinity chromatography and gel filtration. These proteins, which we named
