    • The current invention is directed to a method for determining amino acid sequence mutations in a produced polypeptide, comprising the following steps of a) providing a sample of a produced polypeptide, b) incubating the polypeptide in the sample with a protease, c) performing a two dimensional analysis using reversed phase chromatography coupled with a high resolution mass spectroscopy (FT-ICR / FT-orbitrap) and MS/MS analysis of the amino acid sequence fragments of the peptides, d) data evaluation by comparing the LC-MS data sets obtained for the samples side by side with the data set of a reference sample, by searching for differences in the signal intensities at given retention times and by evaluation of differential signals with respect to amino acid sequence mutations. The reference sample for data evaluation (d) can be either a well characterized standard or one of the samples to be analyzed.
    • 本发明涉及一种用于测定产生的多肽中的氨基酸序列突变的方法,包括以下步骤:a)提供产生的多肽的样品,b)将样品中的多肽与蛋白酶一起孵育,c) 使用反相色谱与高分辨率质谱(FT-ICR / FT-orbitrap)相结合的二维分析和肽的氨基酸序列片段的MS / MS分析,d)通过比较LC-MS数据集进行数据评估 通过在给定的保留时间上搜索信号强度的差异,并且通过评估关于氨基酸序列突变的差异信号,将样品与参考样品的数据集并排获得。 用于数据评估的参考样本(d)可以是一个良好表征的标准或要分析的样品之一。
