  • Publication number: 20040235062
    Abstract: A method is disclosed for identifying or analyzing, easily and in a short time, the molecular weight, the chemical species of molecules, and the structure of molecules, of a protein present on the superficial layer of cells or in cells, or a substance interacting with the protein. This method comprises the steps of: bringing the cells having the protein and the substance interacting with the protein into contact with each other to cause the substance to interact with the cells; purifying the cells, with the cells and the substance in an interacting state; irradiating the purified cells with a laser to ionize the substance directly; and analyzing the ionized substance by mass spectrometry.
