Evans blue permeability
WebTherefore, Evans blue dye (EBD), an albumin-binding fluorescent tracer that is simple to detect and quantify, has been widely utilized for studying BEnd permeability during BBB … WebEvans blue staining is used to check the integrity of the cell membrane. Because of the semipermeable property of the cell membranes, living cells exclude the dye. But damaged cells are unable to eliminate the dye and so are stained blue [58]. The absorbance of the extracted Evans blue is increased with an increase in cell membrane damage.
