Eosin B (C.I. 45400)
Eosin B (C.I. 45400) is a readily water-soluble, red dye with a green fluorescence (λmax. 514 nm), which is commonly used in histology and microbiology. The dye binds in the acidic pH range (pH 2.5 – 3.5) to proteins. This complex absorbs light at 536 – 544 nm. The shift of λmax. is proportional to the protein concentration. The dye-protein complex forms immediately and is stable for 2 hours.
