PCT No. PCT/GB94/01533 Sec. 371 Date Apr. 24, 1996 Sec. 102(e) Date Apr. 24, 1996 PCT Filed Jul. 15, 1994 PCT Pub. No. WO95/02825 PCT Pub. Date Jan. 26, 1995Disclosed is a method for measuring or detecting inorganic phosphate ion in a sample. In the method, a sample is reacted with a phosphate-binding protein containing (i) an inorganic phosphate ion binding site and (ii) a detectable label that produces a signal whose amplitude changes detectably upon the binding of inorganic phosphate ion to the binding site, under conditions effective to allow binding of phosphate in the sample to the binding site. From a change in signal, the level of inorganic phosphate ion is measured or detected. Also disclosed are phosphate binding proteins for use in the method. |
