Description & Specifications


Substrate Type AP Fluorescent
Substrate Quantity 3 x 36mg

  • Produces a low fluorescence signal until enzymatically acted upon, yielding detection of AP to 0.1 attomole
  • Provides low background
  • Offers linear kinetics over five orders of magnitude of AP concentration
  • Has an unusually large Stokes' shift (≈120nm), which leads to higher detection sensitivity
