For incoming MTAs (since the owner of the research material will determine the conditions under which he wishes to share the material with our university), the PI/PI department should back up the MTA proposed by the owner of the research material that an MTA the size of a few hundred words on a page can contain up to several thousand words over a dozen pages. The Simple Letter Agreement for the Transfer of Materials (Box 3 [see end chapter] of the NIH) is an excellent example of a short, easy-to-understand and one-sided MTA. The Simple Letter Agreement does not require negotiations and is used by academic institutions in the United States to transfer material, and in the case of research consortia composed of several academic or non-profit institutions, this type of agreement can be modified to create an umbrella for the simple transfer of material between consortia. At the other end of the spectrum, a complex and long MTA of a company ready to supply innovative and highly owner-owned materials can take years to negotiate. A material transfer contract (MTA) is a contract that governs the transfer of research material between two organizations when the recipient intends to use it for his or her own research purposes. The MTA defines the rights of the supplier and the rights and obligations of the recipient with respect to materials and all offspring, derivatives or modifications. Biological materials such as reagents, cell lines, plasmids and vectors are the most frequently transferred materials, but MTAs can also be used for other types of materials such as chemical compounds, mouse models and even certain types of software. After the execution of an MTA, PI is responsible for the agreement with the supplier or recipient for the transport and delivery of the requested material. Transportation costs, if charged, should be covered by the research team or the Pi department. In the event of a public health emergency, it will be important to ensure that samples and associated data can be moved, accessed and used for many important purposes, including identifying and characterizing the officer responsible, diagnostic objectives, clinical decision-making, epidemiology and the development or validation of diagnostic tools.
