name:NFP
Composition: 1,8-naphthalimide derivative
Excitation / emission wavelength: 403 / 506nm Application: Zn 2 + detection
Storage conditions: -4℃
Other instructions: Half shelf life in sealed state [Main advantage] In DMSO / H2O solution (9 / 1, v / v, pH 7.4, HEPES buffer, 0.2 mM), NFP showed high selectivity and rapid response to Zn 2 + (30 s) with significant fluorescence enhancement. The detection limit (LOD) of zinc ions for NFP is 39 nM, which is well below the WHO standard (76.0 μ M). The binding ratio of NFP to Zn 2 + ions was 1:1, and the binding constant of NFP-Zn 2 + was 1.18 105 M 1.
