IUPAC Name: 3,6-diamino-9-(2-((3-carboxypropyl)(methyl)carbamoyl)phenyl)-5-sulfoxanthylium-4-sulfonate
InChIKey: PNCUNWSKHFBORG-UHFFFAOYSA-N
SMILES: O=C(CCCN(C)C(C1=C(C2=C(C=CC(N)=C3S(=O)(O)=O)C3=[O+]C4=C2C=CC(N)=C4S(=O)([O-])=O)C=CC=C1)=O)O
Biological Activity: ATTO 488 carboxylic acid is a bright green fluorescent dye with high photostability, which is commonly used in protein fluorescent labeling, single-molecule fluorescence imaging and super-resolution microscopy studies. The carboxylic acid form of ATTO 488 can be covalently coupled to primary amines of proteins via activation, or prepared into a maleimide derivative for coupling with thiol groups; it emits green fluorescence after labeling. Ex/Em = 488/524 nm[1][2][3].
