Abstract:
1. A method for detecting a phosphomacromolecule in a sample comprising: (a) contacting the sample with a phosphoaffinity material comprising titanium dioxide, under conditions wherein the phosphomacromolecule is capable of binding to the phosphoaffinity material to form a phosphomacromolecule-phosphoaffinity material complex, wherein the phosphoaffinity material further comprises a support and wherein the support is selected from the group consisting of a particle, bead, gel, matrix, membrane, filter, fiber, sheet, mesh, frit, resin, sample vessel, column, pipette tip, slide channel, and MALDI-TOF plate; and (b) detecting formation of the phosphomacromolecule-phosphoaffinity material complex, thereby detecting the phosphomacromolecule in the sample.
