About our work

The Flow Cytometry Core Facility at the National Eye Institute provides flow cytometry analytical and sorting equipment and services to the NEI Intramural community. Flow cytometry is a technique for counting and examining microscopic particles, such as cells and beads, by suspending them in a stream of fluid and passing them by a detection apparatus. The Core utilizes state-of-the-art sample preparation, data acquisition and analysis, and sorting procedures in providing service and supporting collaborative research projects. The Core provides training to students, fellows, and principal investigators at NEI in the theory and practical use of the technology. The training includes sample preparation, staining, and handling post sort.
