Figure 2From: Development of an in vitro model to measure bioactivity of botulinum neurotoxin A in rat bladder muscle strips A-B: Bladder strip contractions after BoNT-A incubation. A: Response of bladder strip contraction force (mN) to KCl, CCh, EFS before and after 0.3 nM BoNT-A incubation (run 1a). B: Response of bladder strip contraction force (mN) to KCl, CCh and EFS during Krebs perfusion (run 1b = control).Back to article page
