- CAS No.: 174568-67-3
- Formula:C28H23N3O5
- Molecular Weight:481.50
IUPAC Name: 2-(3,6-bis(dimethylamino)xanthylium-9-yl)-4-(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)benzoate
InChIKey: KTVDADGGDFOITB-UHFFFAOYSA-N
SMILES: O=C(C1=C(C2=C3C=CC(N(C)C)=CC3=[O+]C4=C2C=CC(N(C)C)=C4)C=C(N5C(C=CC5=O)=O)C=C1)[O-]
Biological Activity: Tetramethylrhodamine-5-maleimide is a fluorescent probe with high specificity for cysteine thiol (SH) groups. Tetramethylrhodamine-5-maleimide has high sensitivity, responds rapidly to negatively charged nanoparticles, and shows a concentration-dependent decrease in fluorescence intensity, but it is susceptible to interference from humic acids[1].
