ABSTRACT
TMAs have helped scientists and clinicians that collect and bank tissue samples to share their valuable resources. Tissue samples can be subdivided to enable more studies, which should lead to more collaboration and access to scarce tissue. Private companies (e.g., U.S. Biomax, Rockville, MD, USA and Cybrdi, Rockville, MD, USA) sell TMAs for healthy and diseased human tissue (or a combination of both) at prices ranging from $50 to $1000, depending on the spot density and the amount of associated clinical data that is needed. They also provide incomplete arrays with missing or broken spots at roughly 1/3 of the price of complete arrays for testing new protocols.
