AttoPhos AP Fluorescent Substrate System contains a highly sensitive fluorescent alkaline phosphatase (AP) substrate.|
Sensitivity: Low fluorescence signal until enzymatically acted upon, yielding detection of AP to 0.1 attomole.Low Background: Low fluorescence from interfering biological molecules.Linearity: Linear kinetics over five orders of magnitude of AP concentration. Additional Features: Excitation at 435nm, emission at 555nm and large Stokes' shift (≈120nm).
