Chemical Name	2-[(5-Fluoresceinyl)aminocarbonyl]ethyl Methanethiosulfonate
Synonyms	Methanesulfonothioic Acid S-[3-[(3',6'-Dihydroxy-3-oxospiro[isobenzofuran-1(3H),9'-[9H]xanthen]-5-yl)amino]-3-oxopropyl] Ester; MTS-4-Fluorescein
Molecular Formula	C₂₄H₁₉NO₈S₂
Molecular Weight	513.54
Appearance	Yellow to Pale Orange to Red Solid
Melting Point	>162°C dec.
Storage	-20°C, Inert atmosphere
Solubility	DMSO (Slightly), Methanol (Slightly)
Applications	A thiol specific fluorescent probe useful for ion channel and protein topology research. The recently available MTS-fluorophores may find application in the real-time monitoring of conformational changes, since fluorophores coupled to introduced cysteines can change their fluorescence during a conformational change. Fluorescence lifetime may also yield information regarding distances and molecular motion in a protein molecule.Fluorescence: max. Abs. 492nm; max. Em. 515nm; e x 10-3: 75
