What We Do

The Media Prep Facility feeds Janelia research. Experienced staff provide a consistent supply of quality-assured media and reagents, and a wide variety of fly food products, to support laboratories and team projects. We customize formulations and protocols to precisely fit the needs of Janelia research.

A majority of the Facility's work involves fly food, but we also provide bacterial and other media products to all of Janelia. The Facility fulfills and delivers orders to the labs quickly. Because commercially-available media products are available in the Janelia stockroom, the Media Facility has flexibility to produce individualized products that are not commercially available.
