Some sharp entrepreneur will take up the call and produce these snails commercially. Conotoxins can furthermore be functionalised and provide outstanding leads for new molecular probes: In another paper published in the "Australian Journal of Chemistry," the researchers developed a new methodology to label conotoxins and use them to visualise ion channels in cells. The snail also detects chemicals released from its prey in the water. The snail insulin is not identical to the human type, but it's similar enough that its discovery has excited scientists.
