Fast Green FCF

Fast Green FCF is a dye used to stain proteins for IEF (isoelectric focusing) and SDS-PAGE. When bound to proteins, Fast Green FCF fluoresces near infrared (absorption maximum: 624 nm). Fast Green FCF staining is linear over a wider range of protein concentrations compared to Brilliant Blue R.Formal Name: N-ethyl-N-[4-[[4-[ethyl[(3-sulfophenyl)methyl]amino]phenyl](4-hydroxy-2-sulfophenyl)methylene]-2,5-cyclohexadien-1-ylidene]-3-sulfo-benzenemethanaminium, disodium salt.
