The electron microscopy (EM) laboratory team uses transmission electron microscopy (TEM), scanning electron microscopy (SEM), negative staining techniques and assays, immunogold labeling, quantitation of biological samples, and other specialized methods. The EM team at the Integrated Research Facility at Fort Detrick (IRF Frederick) uses these varied capabilities for the analysis of biological samples at an ultrastructural level.
Main Areas of Focus
The EM laboratory team focuses on the analysis and diagnosis of virus-infected tissues, cells, supernatants, and purified preparations.
Capabilities
- Custom protocols based on specific sample types and study goals
- Fresh chemical fixatives and custom reagents
- Precise protocols and methods for sample preparation
- Analysis and scientific evaluation of tissues, cells, and suspension samples
- Immunolabeling and virus quantitation assays
- High-resolution digital images from transmission and scanning electron microscopes
- Data interpretation and analysis
- Publication-quality data reports and analyses
