Creative Bioarray now provides in vitro neurotoxicity assays including neurite outgrowth assay and high throughput microelectrode array to study the effects of chemicals on the morphology and electrophysiological activity of neurons.
Neurotoxicity represents negative effects of chemicals on the nervous system that can lead to prolonged or even permanent troublesome consequences, especially on the developing central nervous system. These consequences can include headache, delusions, loss of memory and/or vision, seizures, behavioral changes, mental retardation, and other mental issues, which, when revealed, are usually irreversible after a long term exposure.
Due to the imperceptibility of neurotoxicity, most of the project closures due to neurotoxic issues occur in the clinical phase, while safety issues related to other organs can be addressed much earlier in the drug development process. Late stage project closure leads not only to higher cost of time and money for drug developers, but also to greater risks for patients. Therefore, evaluating toxic effects of drugs on the nervous systems is of great importance in toxicological studies.

Compared to animal tests (for example, TG 418, TG 419, and TG424), cell-based in vitro assays are way faster and much cheaper, which can also provide more information on the mechanisms at the same time, thus are more suitable for early stage high throughput screening.
Creative Bioarray provides in vitro neurotoxicity assays based on cultured neural cells for greater predictivity. We use automated high-content imaging or live-content imaging for neurite outgrowth assay to monitor early markers of neurotoxicity, and microelectrode array to accurately monitor the electrophisiological activity of the neurons.
