US Patent 7,208,573. Enrichment of phosphate peptides for proteomic analysis. Inventor: Karla Robotti. Assignee: Agilent Technologies
Invention pertains to a method for separating phosphorylated peptides from a mixture of phosphorylated and unphosphoryated peptides. A kit is included in the invention. According to the abstract, a collection of peptides, some with one or more phosphate groups, is reacted with a first resin. They are then reacted with a capture ligand, which reacts with the phosphate group of the phosphorylated peptides to form a bond. Phosphorylated peptides are separated from unphosphorylated peptides with the capture ligand.
US Patent 7,208,268. Differential phage capture proteomics. Inventor: Paul Stroobant. Assignee: Not available

US Patent 7,202,471. Method and apparatus for mass spectrometry. Inventors: Toshinobu Hondo; Jun Tamura. Assignee: JEOL
The method starts with gaining a total ion chromatogram via mass spectrometry. A desired mass peak from the displayed accumulation mass spectrum is chosen. “Another mass chromatogram coincident in elution start time, maximum elution time, and elution end time with the mass chromatogram of the selected mass peak are extracted and selected out as a mass peak,” according to the abstract, and a mass spectrum of a single component is reconstructed.
