  • Storage Instruction:
  • Store at -20°C
  • Note:
  • Maximum Excitation/Emission wavelengh: 496/506 nm (in Ethanol)

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