Can I edit or change the terms of the MTA?

The Addgene team can help you update contact information on the implementing letter of the MTA, such as the recipient scientist or Principal Investigator name and address details. Simply contact us at with your requested changes and we will create a revised copy of the MTA for signature.

Any terms listed on the UBMTA itself cannot be edited. Addgene is required to use the unedited UBMTA for all plasmid transfers between the providing institutions and the recipient institutions. Addgene helps to gather the signatures and facilitate the MTA approval process but we cannot make any changes to the UBMTA. If you or your legal department has questions about the terms of the UBMTA, please contact us at
