(R)-2-[(5-Fluoresceinyl)aminoc

1) Cat. No.: TRC-F510500; 2) Chemical Name: (R)-2-[(5-Fluoresceinyl)aminocarbonyl]-2-trimethylammoniumethyl Methanethiosulfonate, Bromide Discontinued; 3) CAS No.: ; 4) Mol. Formula: C27H27BrN2O8S2; 5) Mol. Weight: 651.55; 6) Packing Size: 5mg / 50mg; 7) Appearence: ; 8) Application Notes: 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 ; 9) Synonym: MTSET-Fluorescein; 10) Solubility: ; 11) Storage condition: ; 12) References: Mannuzzu, L.M., et al.: Science, 271, 213 (1996), Goulett, C.C., et al.: JBC, 273, 45, 30012 (1998), Adams, C.M., et al.: JBC, 273, 46, 30204 (1998)
