A new animal- and cell-free method has been developed to measure the toxic activity of Botulinum neurotoxin (BoNT), e.g. Botox. The invention will avoid the use of mouse LD50 tests for toxicity testing, e.g. in BoNT-containing pharmaceutical products such as Botox.
The method uses functionalized liposomes to determine the toxin’s activity under physiological conditions. A press release about the technology has been published here (article in German).
