Recombinant DNA……To Exempt or Non-Exempt…….That is the Question?
By Debra Howeth, MPH
What is recombinant DNA (rDNA) you may be asking yourself? The National Institutes of Health Office of
Biotechnology Activities (NIH-OBA) defines rDNA molecules as either: (i) molecules that are constructed
outside living cells by joining natural or synthetic DNA segments to DNA molecules that can replicate in a
living cell, or (ii) molecules that result from the replication of those described in (i) above. In other
words, it is genetically engineered DNA prepared by transplanting or splicing genes from one species
into the cells of a host organism of a different species. Such DNA becomes part of the host's genetic
makeup and is replicated.
The Recombinant DNA Program of the NIH-OBA promotes scientific advancement and safety in the
conduct of basic and clinical rDNA research. The NIH Guidelines for Research Involving Recombinant
DNA Molecules (Guidelines) provides standards guiding containment and safe research practices for
rDNA. As a condition for NIH funding of recombinant DNA research, institutions shall ensure that such
research conducted at or sponsored by the institution, irrespective of the source of funding, shall
comply with the NIH Guidelines. This means that even if you are not receiving NIH funding you are still
required to conform to the NIH Guidelines for rDNA. The penalty of non-compliance by any researcher
at the institution will result in: forfeiture of funding; suspension or other limitation of financial
assistance; and a requirement for prior NIH approval for any or all rDNA projects at the institution.
The Guidelines require that institutions ensure that the research is conducted in full conformity with the
provisions of the NIH Guidelines. This is the responsibility of the Institutional Biosafety Committee (IBC).
At the University of South Florida, the IBC requires registration for the use, possession, storage, and/ or
transport of infectious agent(s) (e.g. bacteria, viruses, parasites, fungi, protozoa, prions, etc.), biological
toxin(s), recombinant DNA (rDNA) and/or Select Agent(s)/Toxin(s) regulated by the CDC and/or the
USDA.
So you may be thinking……now what?? How do I know where my research falls under these Guidelines?
The first thing that you might do is cruise over to the NIH-OBA website to review the Guidelines for
rDNA. Once you have perused the Guidelines, you will realize that the Guidelines are long and very
complicated and there are some questions to ask yourself before you can determine where your
research falls in terms of the Guidelines. The scope of the rDNA work will determine what type of
registration for your rDNA work is necessary.
Here at USF, IBC registration of rDNA falls into two categories: Exempt (Requires IBC Notice
Simultaneous with Initiation) and Non-exempt (Requires IBC Approval before Initiation). The Exempt
applications are reviewed through an expedited process within 5 business days and can be submitted at
anytime. Non-exempt applications require review by the full IBC at their monthly meeting. Deadlines for
submission and the IBC meeting schedule can be found at
http://www3.research.usf.edu/dric/biosafety/meeting-schedule.asp.
So how do you know which category your research falls into? Does your research involve….

A construct contain viral DNA that represents more than 2/3 of any eukaryotic viral genome








Using risk group 2, 3, or 4 agents as host or vector
Cloning DNA for risk group 2, 3, or 4 agents into nonpathogenic prokaryotic or lower
eukaryotic host-vector systems
Using infectious or defective DNA or RNA viruses in the presence of helper virus in tissue
culture systems.
Creation of transgenic animals or plants
Using more than 10 liters of culture.
Cloning of toxin molecules with LD50 of less than 100 ng per kg of body weight.
Deliberate transfer of recombinant DNA, or DNA or RNA derived from rDNA into one or more
human subjects.
Deliberate transfer of a drug resistant trait to microorganisms not known to acquire this trait
naturally, if such acquisition could compromise the use of the drug to control disease agents in
humans, veterinary medicine, or agriculture.
If you can answer “No” to all of these questions, then your rDNA research falls into the exempt
category. Some examples of exempt rDNA work would include: 1) The use of plasmids to transfect a cell
line to express a gene of interest such as luciferase for imaging. 2) The insertion of rDNA into an
expression host such as E. coli K12. On the other hand a “Yes” answer to any of these questions would
require the submission of a non-exempt rDNA application. Some types of experiments that would fall
into this category would be: 1) Creation of transgenic mice by inserting rDNA into the germ line of the
mouse. 2) A viral vector (including viral vector kits) used to transport rDNA into an animal or cells. 3)
rDNA used in a human subject such as a viral vector vaccine to deliver a gene of interest.
