cytena GmbH is a spin-off company of the University of Freiburg. The team provides a single-cell printer for isolation of single living cells. The single-cell printer is supported by an automated imaging process to encapsulate cells in droplets, which are delivered to any type of substrate, e.g. 96 and 384 well plates. Thanks to this particularly gentle isolation method, high viability of the single cells after the printing is assured and the cells can thus either be analyzed thereafter or grown into clonal colonies. To assure clonality, multiple images are recorded during the process. Cross-contamination is avoided by the use of disposable cartridges. Single cells are required for the development of state-of-the-art drugs, so-called biologicals as well as for cell line development and the genetic analysis of single cells for cancer and stem cell research.
