The immunology team interrogates immune responses against pathogens requiring maximum containment by use of a variety of capabilities. These include but are not limited to cytometry (e.g., immunophenotyping), Luminex multiplex protein/cytokine arrays, cartridge-based cell- sorting (MACSQuant Tyto), ELISAs, serology, in vitro functional assays, intracellular cytokine staining (ICS) enzyme-linked immune absorbent spot (ELISPOT; e.g., T cell and B cell).
Main Areas of Focus
- Immunophenotyping and immune kinetics
- Pathogen-specific serology
- Multiplex cytokine assays and analysis
- In vitro functional assays
Capabilities and Specialized Equipment
- Custom pathogen-specific assay development
- Pathogen-specific prescreening
- Data interpretation and analysis

Erika and Tony work in the biosafety cabinet within the BSL-4 laboratory to isolate and stain cells attained from tissues collected during necropsy; subsequently, the cells will be analyzed via flow cytometry.
Rebecca processes a stained and fixed whole-blood sample on the Cytek Aurora Flow Cytometer in the BSL-2 laboratory.
Tony prepares a chamber slide in the BSL-2 laboratory. These slides are used for imaging with the ONI Nanoimager S super-resolution microscope.
