FlAsH-EDT2

1) Cat. No.: TRC-F335200; 2) Chemical Name: FlAsH-EDT2; 3) CAS No.: 212118-77-9; 4) Mol. Formula: C24H18As2O5S4; 5) Mol. Weight: 664.5; 6) Packing Size: 25mg / 250mg; 7) Appearence: White to Pale Orange Solid; 8) Application Notes: The Fluorescein Arsenical Hairpin Binder (FlAsH) method is presented for fluorescence labeling of proteins in living cells. Labeling proteins with the membrane-permeant fluorogenic biarsenical dye fluorescein arsenical hairpin binder-ethanedithiol (FlAsH-EDT2). The membrane-permeant fluorogenic biarsenicals FlAsH-EDT2 and ReAsH-EDT2 can be prepared in good yields by a straightforward two-step procedure from the inexpensive precursor dyes fluorescein and resorufin. ; 9) Synonym: 4',5'-Bis(1,3,2-dithiarsolan-2-yl)-3',6'-dihydroxyspiro[isobenzofuran-1(3H),9'-[9H]xanthen]-3-one; FlAsH; Fluorescein Arsenical Helix Binder; Lumio Green; ; 10) Solubility: Chloroform, Methanol; 11) Storage condition: Amber Vial, -20˚C Freezer, Under Inert Atmosphere; 12) References: Gaietta, G., et al.: Science, 296, 503 (2002), Hoffmann, C., et al.: Nature Methods, 2, 171 (2005), Dyachok, O., et al.: Nature, 439, 349 (2006), Gautier, A., et al.: Chem.
