Abstract
A method for determining metal ions, both qualitatively and quantitatively, is disclosed. The method utilizes emission from fluorescence resonance energy transfer from a luciferase-carbonic anhydrase conjugate or fusion protein to an acceptor ligand in the presence of metal ion bound to the protein to measure free metal ion concentrations down to picomolar concentration ranges. The method is relatively insensitive to contaminants, and so can be used to measure metal ion concentrations in cells, body fluids or environmental samples without extensive sample preparation.
