Replacement of the Mouse LD<sub>50</sub> Assay for Determination of the Potency of AbobotulinumtoxinA with a Cell-Based Method in Both Powder and Liquid Formulations

Botulinum neurotoxins (BoNTs) are important therapeutic agents. The in vivo median lethal dose (LD<sub>50</sub>) assay has been commonly used to measure the potency of BoNT commercial preparations. As an alternative, we developed cell-based assays for abobotulinumtoxinA in both powder (D...
