The Nunclon Sphera is a polymer-coated surface with very low-binding characteristics, which is designed to allow many different cell types to grow in suspension consistently with virtually no cell attachment. An alternative to commonly used non-treated surfaces, this non-adherent surface is especially important for researchers seeking to cultivate cancer and stem cell spheroids, since the product is able to grow uniform and dependable spheres. Manufacturer says the surface also offers exceptional quality for embryoid body formation of pluripotent stem cells, providing a reliable tool to investigate cell fate potential and lineage specificity of stem cells.
