Fluorescein leakage assay
Web[collapsed]After peer review, two assays, the cytosensor microphysiometer test and the fluorescein leakage assay, were scientifically validated for being used as an initial step within a top-down approach to identify ocular corrosives and severe irritants from all other classes for the chemical applicability domain of water soluble chemicals. WebThe Fluorescein Leakage (FL) test, a short-term in vitro assay measuring damage on exposure to eye irritants to a transepithelial barrier permeability system, has been assessed as an alternative to the Draize rabbit eye irritation assay in the EU/Home Office international validation trial. The assay is based on the degree of leakage of sodium ...
