Venom A-Z Q is for quinquestriatus

Venom A-Z Q is for quinquestriatus – as in Leiurus quinquestriatus, known by the common name of Death Stalker scorpion. As the name would suggest, Leiurus venom is amongst the most toxic of all scorpions, however it also contains chlorotoxin – a potentially useful peptide that has shown a high affinity for glioblastoma brain tumour cells (as seen on the BBC documentary Pain, Pus & Poison: The search for modern medicine) as well as several potent calcium and potassium channel blockers.
