Title: Toxin; Ricin
Description: Microscopic photographs showing the level of fluorescence (green images) and the numbers of cells (blue images) at the time the cells were exposed to ricin and 6 hours later. Note that the fluorescence has decreased (more black regions in the bottom left photo) while the cell count remains virtually the same. This shows that the NIST assay detects ricin even before significant cell death occurs.
