How to Request Plasmids

All plasmid requests must be placed on-line.

Addgene accepts requests ONLY from academic or non-profit organizations. If you are from a commercial entity, we can direct you to a contact person at the institution that provided the plasmids. Some institutions can provide the plasmids to you under an MTA.
