A high-throughput approach for measuring intracellular ATP levels to access compound-mediated cellular toxicity
Many drugs fail in clinical trials due to toxicity-related issues; therefore, drug-mediated cellular toxicity should be determined at an early stage in the drug discovery value chain. There are many assay systems that can be utilised to measure cellular toxicity. In this article we demonstrate that intracellular ATP concentrations are…

Application note: Production of human induced pluripotent stem cell-derived cortical neurospheres in the DASbox® Mini Bioreactor System
There is substantial interest in the scientific community in using human induced pluripotent stem cell (hiPSC)-derived neural cells to study basic mechanisms of brain development, neuronal function, and drug-induced effects. In vitro-generated brain organoids are promising models, because they show a remarkable degree of maturation and can be kept in…
