Assay Development Services

SCIENION offers innovative, complete and flexible solutions for multiplex assay development and optimization for any application in Diagnostics and Life Sciences.

Customers can rely on our longstanding in-depth experience in all aspects of successful multiplex assay development, covering the whole range from surface functionalization, printing and immobilization, optimization of incubation protocols, detection and data analysis.

Due to our unique sciFLEXARRAYER technology – the best choice for precise ultra-low volume liquid dispensing – customers benefit from developed cost-saving miniaturized assays. We also offer the transfer of already existing assays to the SCIENION platform – including multiplexing and miniaturization.
