The National Institute of Environmental Health Sciences (NIEHS) requires a 12-month subscription to the Cytobank Flow Cytometry Analysis Platform to support its Flow Cytometry Center. The requirement includes one Academic subscription to a private NIEHS Enterprise Cytobank environment and ten Academic Additional User licenses. The platform will be used to catalog, manage, analyze, interpret, and share flow cytometry experimental data for NIEHS intramural and trans-NIH researchers.
