Cultures of bovine pulmonary endothelial (BPE) cells were exposed to LC70 doses of ricin or abrin (15.5 and 4.5 pM respectively) over a period of up to 40 h. The viability of the cultures (as determined by the neutral red (NR) dye retention assay) declined after 6 h exposure to the toxins. From 15 h
Abrin, a phytotoxin obtained from the seeds of the Abrus precatorius plant, is highly toxic with an estimated human fatal dose of 0.1—1 μg/kg. In this study, abrin was purified and characterized through SDS PAGE and mass spectrometry analysis; further study on toxicity was carried out to investigate
