Micro-bridges for sitting-drop crystallizations

Micro-bridges, small devices in the shape of a bridge, have been designed to carry out sitting-drop crystallizations on a microscale. Micro-bridges have an indentation in the top of the bridge to contain the protein drop during a crystallization experiment and to prevent the droplet from spreading over a large area. The special feature of micro-bridges is that they fit into the wells of standard tissue-culture multiwell plates.
