Fumonisin B2
Fumonisin B2

Artikelnummer: Cay13227-1

Fumonisin B2 is a mycotoxin originally isolated from F. moniliforme, a prevalent fungus of corn and other grains. Fumonisins cause food poisoning in livestock and humans following the consumption of Fusarium-infested corn. Fumonisin B2, like fumonisin B1 (Cay-62580), structurally resembles sphingosine and, at 1 µM,...

alpha-Bungarotoxin

Artikelnummer: Cay16385-1

alpha-Bungarotoxin is a snake venom-derived toxin that irreversibly binds nicotinic acetylcholine receptors (Ki = ~2.5 µM in rat) present in skeletal muscle, blocking action of acetylcholine at the postsynaptic membrane and leading to paralysis. It has been widely used to characterize activity at the neuromuscular...
