Apamin Apamin Apamin is an 18 amino acid peptide neurotoxin found in apitoxin (bee venom). Dry bee venom consists of 2–3% of apamin. Apamin selectively blocks SK channels, a type of Ca-activated K channel expressed in the central nervous system. Toxicity is caused by only a few amino acids, these are cysteine, lysine, arginine, arginine and histidine. These amino acids are involved in the binding of apamin to the Ca-activated K channel. Due to its specificity for SK channels, apamin is used as a drug in biomedical research to study the electrical properties of SK channels and their role in the
Vickers Venom "3" on the fuselages sides, the Venom was painted a cream colour for exhibition purposes. The need to concentrate on the Spitfire led to the scrapping of the sole Venom prototype in 1939, after a crash in testing. Vickers Venom The Vickers Type 279 Venom was a low-wing monoplane single-seat, single-engined, eight-gun fighter, powered by a radial engine. It was fast and manoeuvrable but its engine lacked the power and development potential of its Merlin-powered competitors. Only one was built. The Vickers Venom was designed to meet Air Ministry specification F.5/34 which called for a single-seat eight-gun aircraft with the
