NIST Researchers 'All Aglow' Over New Test of Toxin Strength

Caption

Microscopic photographs showing the level of fluorescence (green images on left) and the numbers of cells (blue images on right) at the time the cells were exposed to ricin (top row) and six hours later (bottom row). 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.
