Use network co-culture assays to replicate the in vivo physiological and morphological conditions in addition to desired cellular makeup.
Co-Culture Network Design Library
By incorporating natural tissue regions within the network topology, the co-culture networks allow study of cell and drug behavior at and across the interfaces. The co-culture network constructs are available with several options for channel size, tissue region scaffolding, and barrier design. We can help you select the right parameters for your needs and can also construct custom designs if needed.
The SynVivo platform can support custom assays based on your research application. Don’t see a catalog assay for your biological question? Want to perform your assay using a linear chip design? We can develop a custom assay kit for you using our library of chip designs- See more information in the following tabs.
