# Is the VitroGel compatible with drug/compound treatments?

Yes, the VitroGel hydrogels are a great system to build 3D cell models for drug/compound screening. VitroGel is compatible for high-throughput screening with an auto liquid handling machine. Molecules can be mixed with the hydrogel or be added directly from the top of the hydrogel. This will allow an easy diffusion through the gel.
