85-1608-97　Bis(dithiarsolanyl)-bis(sulfobutyl) Cyanine 3 1mg　CAS No:946135-47-3　004158

特徴

• 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.
