1) Cat. No.: TRC-B431900; 2) Chemical Name: Bis(dithiarsolanyl)-bis(sulfobutyl) Cyanine 3; 3) CAS No.: 946135-47-3; 4) Mol. Formula: C35H46As2N2O6S6; 5) Mol. Weight: 932.98; 6) Packing Size: 1mg / 10mg; 7) Appearence: ; 8) Application Notes: A red Cy3-based biarsenical fluorescent probe targeted to a complementary binding peptide. AsCy3 has good photostability, low pH sensitivity, high absorbance, and good quantum yield. This new probe provides a FRET partner to biarsenical dye FlAsH, making this discovery an important step toward a whole toolkit of colored probes directed to different small peptide motifs.; 9) Synonym: 5-(1,3,2-Dithiarsolan-2-yl)-2-[3-[5-(1,3,2-dithiarsolan-2-yl)-1,3-dihydro-3,3-dimethyl-1-(4-sulfobutyl)-2H-indol-2-ylidene]-1-propen-1-yl]-3,3-dimethyl-1-(4-sulfobutyl)-3H-indolium Inner Salt; AsCy3;; 10) Solubility: ; 11) Storage condition: ; 12) References: Cao, H., et al.: J.
