Biosafety level 2 organisms or cells or tissues, (including most human, non-human primate, or other mammalian cells) at 乐播传媒 College requires approval of the Institutional Biosafety Committee. Work with Biosafety Level 3 or 4 organisms is not permitted on campus. If you are uncertain about the classification of the organisms you are working with, please check the following database:

Work with recombinant DNA also requires approval from the Institutional Biosafety Committee. Even rDNA work that is exempt is expected to have an official 鈥淓xempt鈥� letter.  Please consult this flowchart to aid with differentiating between exempt and non-exempt experiments.  The ONLY rDNA experiments that are exempt from review are rDNA molecules that are not in organisms or viruses or:

VIII鈥慒鈥�2         rDNA molecules that consist entirely of DNA segments from a single nonchromosomal or viral DNA source, though one or more of the segments may be a synthetic equivalent.

VIII鈥慒鈥�3         rDNA molecules that consist entirely of DNA from a prokaryotic host including its indigenous plasmids or viruses when propagated only in that host (or a closely related strain of the same species), or when transferred to another host by well-established physiological means.

VIII鈥慒-4         rDNA molecules that consist entirely of DNA from a eukaryotic host including its chloroplasts, mitochondria, or plasmids (but excluding viruses) when propagated only in that host (or closely related strain of the same species).

VIII鈥慒鈥�5          rDNA molecules that consist entirely of DNA segments from different species that exchange DNA by known physiological processes, though one or more of the segments may be a synthetic equivalent.

VIII鈥慒鈥�6        rDNA experiments that do not present a significant risk to health or the environment as determined by the NIH Director, RAC and following appropriate notice and opportunity for public comment.
