Gene Delivery Core

The Gene Delivery Core was established in 2001 and has been supported over the years by the Program Project Grant from NHLBI. The Core's objectives are to provide investigators with access to state-of-the-art vector technology for basic research applications, to support investigators in the use of gene transfer, RNAi, protein expression and purification, and other molecular biology techniques. This objective is achieved:

  1. Through development of the new vector systems for gene delivery and gene expression.
  2. By providing molecular biology services including vector construction, virus production, and protein expression and purification.
  3. By providing the expertise to investigators, including project design and troubleshooting existing projects.
  4. By maintaining a collection of prokaryotic and eukaryotic vectors.


▼   Service Request

To request a service, please schedule an appointment with Director of the Gene Delivery Core, Dr. Mikhail Alexeyev. At the meeting, your gene delivery options will be discussed, including project design and choice of the vector.


Before service associated with generation of new recombinant DNA (rDNA) molecules can be initiated, investigators at the University of South Alabama must submit to the Institutional Biosafety Committee (IBC) a rDNA protocol, which covers construction of these molecules. The protocol must include the Director and Personnel of the Gene Delivery Core as associates. A rDNA application can be downloaded here. If you need assistance completing this form, please contact Director of the Gene Delivery Core  by calling (251) 460-6789 or emailing

▼   Plasmid Requests
Vectors are provided either as DNA or as E. coli cultures at discretion of the Core*. The Core is committed to providing materials to investigators outside of the University of South Alabama for basic research purposes. Investigators outside University of South Alabama are requested to execute a Material Transfer Agreement (MTA). Investigators from institutions, which are signatory to UBMTA (the list of signatories to UBMTA can be found here) may execute UBMTA Implementation Letter [PDF]. Investigators from institutions not signatories to UBMTA should execute the following MTA.
