    • The present invention relates to a method for the detection and/or enrichment of a large number of different analyte proteins and/or analyte peptides from a sample mixture which includes proteins and/or peptides. The method includes the following steps: a) provision of the sample mixture and, where appropriate, fragmentation of the proteins contained therein into defined peptides, b) provision of first binding molecules which are specific for a peptide epitope of at least one of the various analyte proteins and/or analyte peptides, whereby the peptide epitope includes up to a maximum of five, preferably two to three, amino acids, c) incubation of the first binding molecules with the sample mixture, and d) detection and/or enrichment of the analyte proteins and/or analyte peptides bound to the first binding molecules. The invention also relates to binding molecules which are specific for the terminal peptide epitope of various peptide analytes, whereby the terminal peptide epitope includes the free NH2 group or the free COOH group, one or more than one amino acid defined by the protease specificity, and in each case up to a maximum of three further terminal amino acids.
    • 本发明涉及从包括蛋白质和/或肽的样品混合物中检测和/或富集大量不同分析物蛋白质和/或分析物肽的方法。 该方法包括以下步骤:a)提供样品混合物,并在适当情况下将其中包含的蛋白质碎裂成定义的肽,b)提供对多种抗原决定簇中的至少一种的肽表位是特异性的第一结合分子 分析物蛋白质和/或分析物肽,其中肽表位包含最多5个,优选2至3个氨基酸,c)将第一结合分子与样品混合物孵育,以及d)检测和/或富集 分析物蛋白和/或与第一结合分子结合的分析物肽。 本发明还涉及对各种肽分析物的末端肽表位特异的结合分子,其中末端肽表位包括游离NH 2基团或游离COOH基团,由蛋白酶特异性定义的一个或多于一个氨基酸,以及 在每种情况下,最多三个其他末端氨基酸。
