  • Specification
  • Product Description:
  • Fluorescent dye derived from trimethine cyanine with an intrinsic single positive charge. Water insoluble and forms reversible disulfide bond with sulfhydryl groups at pH up to 6.5.
  • Storage Instruction:
  • Store in the dark at -20°C and keep under argon.
  • Note:
  • Maximum Excitation/Emission wavelength: 545/565 nm (in CH3OH)

  • Features:
  • Due to its extreme selectivity, the amine-cross labeling is avoided. The pyridyl disulfide bond can be cleavaged by TCEP (tris-(2-carboxyethyl)phosphine hydrochloride) and DTT (1,4-dithiothreitol).
