Addgene recommends that scientists place their own orders, as they will need to fill out the required MTA forms. However, purchasing agents can also order on behalf of scientists. When you place the order, please make sure you have the requesting scientist's name and email, as well as the Principal Investigator's name so that the MTAs will be generated correctly. Entering incorrect information at checkout will delay the MTA approval process. If you are using a PO, you can find more information about POs on our purchase order page.
