Criteria for Protocol Completion and Review

In order to conduct research, teaching, or testing using vertebrate animals at Purdue University, you must have an approved protocol on file with the Purdue Animal Care and Use Committee (IACUC). All protocol applications must be submitted electronically through the Coeus system.

If you are using Coeus for the first time, whether you are Purdue personnel or external to the university, you will need to complete a User Access Request Form found at the following URL:

Once user access has been granted by the Electronic Research Administration office (eRA), you will be able to submit applications through Coeus.

  • Coeus may be accessed by clicking the Launch Coeus Lite button for Academic Users from the website
  • External Users who do NOT have a Purdue Career Account may access Coeus from the website as well. Refer to the second bullet point on the Coeus website.

On the Coeus website, on the top navigation bar, under IACUC Protocols, there are many user guides that will assist you with submitting items through the system.

On the IACUC website, under the Forms button on the left navigation bar, are the forms that should be used when attaching documents to your Coeus submission (e.g., IACUC Protocol Application Attachment and IACUC Form 1A – Amendment). Always use the forms on the website vs. saving the form to your desktop as they are updated regularly.

Please contact the IACUC office at for any questions relating to content of protocol applications. If you need technical assistant with the Coeus system such as training on how to use it, please contact
