Research on microbial agents, which cause lethal diseases in humans and for which effective drugs or preventive vaccines are not available, must be conducted by well-trained investigators in specially built, well-maintained laboratories. The Biocontainment Core provides the triad of customized service, research and development, and education and training to investigators at the university and the wider research community.
To facilitate the transition of the Biocontainment Core into a sustainable state-of-the-art core facility capable of supporting high-caliber research on new, emerging and re-emerging infectious diseases.
Specific Aim 1
- Enhance and streamline core operations.
Specific Aim 2
- Grow and diversify user base, capability and reach.
Specific Aim 3
- Strengthen and sustain core infrastructure.

BSL-3 assays and services
- West Nile Virus plaque assay: Titration of serum samples or tissue homogenates on Vero cells, using traditional agar overlays and neutral red. Calculate virus titers using Excel or your specified output file.
- Homegenate preparation for plaque assay or ELISA: Homogenization of tissue samples using the bead-based Bullet Blender or Fastprep. Clarified samples stored frozen in the facility until used for the plaque assay, ELISA, or other assays.
- West Nile virus PRNT assay: Determination of PRNT90 values for serum samples. Raw data and calculated values returned to the user in Excel or specified output file.
- Luminex assay: Plate set-up, incubation of your samples with beads from your kit, and running of plate on the Luminex 200 instrument in our facility. Raw data files returned in Excel or your specified output file. Samples accepted for testing include: serum, 0.4 microM filtered tissue homogenate, and cell supernatant. Other specimens subject to approval from the Laboratory Director.
- Virus production: Culture, titration, and working dilution determination of West Nile virus or other IBC approved virus. Vials will be stored in our facility until needed for assays.
- Nucleic acid isolation: Isolation of total RNA or genomic DNA for downstream analysis such as RT-PCR. Concentration of each sample determined using UV spectrometry.
- RT-PCR: Plate set up, cDNA synthesis, and running of samples with primers and probes on the real-time PCR instruments. Five different color detection options. Quantitative or relative analysis available.
- Flow cytometry: Creation of single cells suspensions from your tissue samples using the Gentle MACS system, and staining of cells with antibodies. Samples will be fixed and run on the FACS Aria flow cytometer. FACS Aria charges are billed separately.
