    • It is intended to provide an analysis method for a biological sample with clinical significance, which is a system being simple to such an extent that it can be applied to a clinical field, and capable of capping a molecule ionization suppression in mass spectrometry. Mass spectrometry of a biological sample using immunoprecipitation, comprising the steps of: preparing a sample containing an objective biological molecule; concentrating the biological molecule in the sample by immunoprecipitation using an antibody-bound carrier or a carrier to which a molecule capable of specifically binding to an antibody is bound; washing an immunoprecipitate of the biological molecule by using an aqueous solution containing a charge neutralizing agent as a washing liquid; and detecting the biological molecule by subjecting the washed immunoprecipitate to mass spectrometry.
    • 旨在为具有临床意义的生物样品提供分析方法,该方法简单到能够应用于临床领域并且能够在质谱法中限制分子离子化抑制的系统。 使用免疫沉淀的生物样品的质谱法,包括以下步骤:制备含有客观生物分子的样品; 通过使用抗体结合的载体或能够与抗体特异性结合的分子结合的载体通过免疫沉淀将生物分子浓缩在样品中; 通过使用含有电荷中和剂的水溶液作为洗涤液来洗涤生物分子的免疫沉淀物; 并通过对洗涤的免疫沉淀物进行质谱检测来检测生物分子。
