Applications 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. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Cao, H., et al.: J. Am. Chem. Soc., 129, 8672 (2007)

The bis(dithiarsolanyl)-bis(sulfobutyl) cyanine 3 is a molecule that is synthesized by reacting trifluoroacetic acid with the bis(dithiarsolanyl) sulfobutyl cyanine 3. It has been shown to bind to proteins in mammalian cells, and can be used for the detection of recombinant proteins. This molecule also has optical properties that can be detected using an instrument called a spectrophotometer. The bis(dithiarsolanyl)-bis(sulfobutyl) cyanine 3 has been shown to react with cytosolic proteins and disulfide bond. This reaction may lead to the formation of a protein-cyanine conjugate, which can be used as a fluorescent probe for detecting intracellular localization or antigen presence in health effects studies.
