We describe a chemical tag for duplex proteome quantification using neutron encoding (NeuCode). The method utilizes the straightforward, efficient, and inexpensive carbamylation reaction. We demonstrate the utility of NeuCode carbamylation by accurately measuring quantitative ratios from tagged yeast lysates mixed in known ratios and by applying this method to quantify differential protein expression in mice fed a either control or high-fat diet.
我们描述了一种使用中子编码(NeuCode)进行双蛋白质组定量的化学标签。该方法利用了直接、高效且廉价的氨甲酰化反应。我们通过准确测量以已知比例混合的标记酵母裂解物的定量比率,并将此方法应用于量化喂食对照饮食或高脂饮食的小鼠中的差异蛋白质表达,证明了NeuCode氨甲酰化的实用性。
