An antibody or substance that counteracts abrin, a highly toxic protein found in rosary pea seeds.
From 'anti-' (against) + 'abrin' (from 'Abrus precatorius', the rosary pea plant), formed in 20th century medical and toxicology research.
Abrin is so poisonous that a single seed can kill you, and antiabrin research is part of biosecurity science—scientists have to understand toxins deeply enough to create antidotes before bad actors weaponize them.
