Penn Vector Core: Material Transfer Agreements





Material Transfer Agreements


The Penn Vector Core provides materials to academic and other non-profit organizations under a Material Transfer Agreement (MTA). An MTA is required for the transfer of vectors as well as plasmids, cell lines, antibodies, animal models and all other biologicals.

If you do not know whether or not your laboratory currently holds an MTA for the materials requested, please email vector@mail.med.upenn.edu

If your laboratory does not already hold a material transfer agreement (MTA) for the vectors requested, please complete one or more of the MTAs in the links below.

To complete an MTA:

Choose an MTA or MTAs associated with materials requested or anticipated to be requested. For a combination of materials, more than one MTA may be required.

AAV plasmids and vectors based on serotypes 1, 2, 5, 6, 6.2, 7, 8, 9, rh8, rh10, hu11, rh64 and certain others fall under the MTA for AAV, adenoviral vector or lentiviral vector materials (template A).

For all of the plasmids and vectors included in template A plus Allen Institute original materials choose template B.

A specific MTA template is required for the provision of AAV vectors for work involving domain antibodies.

(A) MTA for AAV, adenoviral or lentiviral-based materials

(B) MTA for AAV, adenoviral or lentiviral-based materials Including Allen Institute original materials

(C) MTA for material to be used in applications involving Domain Antibodies

To Complete an MTA Exhibit:

For most of the MTAs listed above, an "Exhibit A" is included in which the following information is requested and for which our recommendations for completion are below:

Original Materials Requested: we recommend selecting as many serotypes and applications of interest for the materials requested to avoid further amendment to this MTA. Humans serotype 5 adenoviral vectors and VSVG pseudotyped lentiviral vectors as well as plasmid DNA may also be listed in MTA (A).

Summary of Research: we recommend listing as many genes/gene families of interest as well as applications of interest for the materials requested to avoid further amendment to your MTA

If additions to the Materials Requested or Summary of Research are needed, an MTA Amendment form may be used. Please note that an MTA (A)  between UPenn and the requesting institution must already be in place to amend additional materials or workplans. For any questions about the form, please email vector@mail.med.upenn.edu.

To complete an MTA Amendment:

For investigators already holding an MTA (A) with UPenn, additional materials or applications may be amended to the existing agreement using the General MTA Amendment form. For investigators wishing to request vectors based on ORIGINAL MATERIALS provided by the Allen Institute, a separate MTA Amendment for Allen Institute Materials is required.

(1) MTA Amendment for additions to Exhibit A

(2) MTA Amendment for Allen Institute Materials

(3) MTA Amendment for 3rd party transfer*

* In order to finalize the Amendment for 3rd party transfer, the recipient should have the 3rd party contact Penn to execute an MTA for the material being transferred.

For completion of all MTAs and MTA Amendments:

The Principal Investigator and an authorized official from the institution  (eg from the institution’s technology licensing or grants & contracts office) should sign where indicated on the MTA and attach the completed Summary of Work. Please note that the MTA should not be signed by students, postdoctoral researchers or fellows.

Our MTAs cannot be substituted by the UBMTA however certain language modifications may be accommodated. For language modification requests, please see the instructions on page 1 of the MTA

For requesting vectors based on Addgene materials:

The Penn Vector Core is pleased to provide vectors based on ORIGINAL MATERIALS distributed through Addgene or sent to us by generous investigators (see Catalog).

The vectors we generate are defined as MODIFICATIONS of the ORIGINAL MATERIALS as defined by the NIH and can be distributed only to investigators that hold an MTA with Upenn and the providing institution for the ORIGINAL MATERIAL.

To request vectors incorporating plasmid DNA obtained through Addgene we require either an MTA with a providing institution facilitated by Addgene, or an MTA directly from the providing institution.

When the original material is available through Addgene: An MTA for the original source material is required. An MTA can be obtained through the process of ordering the original source material through Addgene at www.addgene.org or can be obtained directly from the original providing laboratory / institution. Confirmation of an MTA must be provided to the Vector Core prior to release of the material.

When the original source material is available only from the Deisseroth lab: An MTA for the original source material is required. The Deisseroth Lab policy for sharing materials starts with an email request from the PI of the lab addressed to Dr. Karl Deisseroth (and copied to Charu Ramakrishnan).   The details for requesting MTAs for Deisseroth lab materials can be found on the Deisseroth Lab website. Confirmation of the MTA must be provided to the Vector Core prior to release of the material.


1. ORIGINAL MATERIAL: The material(s) are specifically described in EXHIBIT A of the MTA. ORIGINAL MATERIALS may include for example original plasmid DNA, vectors or cell lines.

2. PROGENY: Unmodified descendants from the ORIGINAL MATERIAL, including but not limited to, virus from virus, cell from cell, or organism from organism.

3. UNMODIFIED DERIVATIVES: Substances created by the RECIPIENT which constitute an unmodified functional subunit or product expressed by the ORIGINAL MATERIAL. Some examples include: subclones of unmodified cell lines, purified or fractionated subsets of the ORIGINAL MATERIAL, proteins expressed/encoded by DNA/RNA supplied by PENN, viral based vectors (assembled particles with or without genomes) generated from DNA/RNA supplied by PENN, or monoclonal antibodies secreted by a hybridoma cell line.

4. MODIFICATIONS: Substances created by the RECIPIENT which contain/incorporate the MATERIAL or which represent a modified form of the MATERIAL, including a molecular modification of the DNA supplied by PENN and/or a viral based vector generated from unmodified or modified DNA supplied by PENN. Some examples include: crosses, breeding varieties, cell fusions, subclonings, viral based vectors generated from both DNA/RNA supplied by PENN and DNA/RNA provided by the RECIPIENT (eg. PENN AAV serotype vectors expressing genes provided by the RECIPIENT) etc.

5. MATERIAL: ORIGINAL MATERIAL, PROGENY, and UNMODIFIED DERIVATIVES. The MATERIAL shall not include: (a) MODIFICATIONS, or (b) other substances created by the RECIPIENT through the use of the MATERIAL which are not MODIFICATIONS, PROGENY, or UNMODIFIED DERIVATIVES.
