3D-FectIN and 3D-Fect are the newest transfection reagents specifically designed and developed for 3D cell cultures. 3D matrices not only add a third dimension to cells’ environment, they also allow creation of significant differences in cellular characteristics and behavior. Because 3D environments are routinely used in basic research and therapeutic applications, OZ Biosciences has developed these two new powerful reagents, 3DFectIN (for hydrogels) and 3DFect (for scaffolds).
