The Glutathione Fluorescent Assay Kit is designed to measure the amount of total glutathione (GSH+GSSG) in cells and tissue homogenates and the total amount (including GSSG and protein mixed disulfides with glutathione) in plasma. The assay is simple and sensitive based on eosinGSH that emits a strong fluorescent signal detectable at 545 nm after excitation at 520 nm.[IMCO Catalog FkGSH-01]
