27 February 2006 Feasibility of detecting peptide phosphorylation by surface enhanced Raman scattering
Author Affiliations +
We report on the feasibility of surface enhanced Raman scattering (SERS) as a highly sensitive technique for detecting peptide phosphorylation. Compared with existing techniques for quantifying peptide phosphorylation, such as high-performance liquid chromatography (HPLC), the short scanning and processing time associated with SERS makes it an attractive alternative for measurement on a near-real-time basis at sub micro-molar concentrations. Using the recently reported drop-coating deposition Raman method we compare our SERS spectra to normal Raman spectra that would otherwise be unobtainable at such low concentration.
