    • The invention relates to antibody reagents that specifically bind to peptides carrying a ubiquitin remnant from a digested or chemically treated biological sample. The reagents allow the technician to identify ubiquitinated polypeptides as well as the sites of ubiquitination on them. The reagents are preferably employed in proteomic analysis using mass spectrometry. The antibody reagents specifically bind to the remnant of ubiquitin (i.e., a diglycine modified epsilon amine of lysine) left on a peptide which as been generated by digesting or chemically treating ubiquitinated proteins. The inventive antibody reagents' affinity to the ubiquitin remnant does not depend on the remaining amino acid sequences flanking the modified (i.e., ubiquitinated) lysine, i.e., they are context independent.
    • 本发明涉及与经消化或经化学处理的生物样品中携带泛素残基的肽特异性结合的抗体试剂。 试剂允许技术人员识别泛素化的多肽以及它们上泛素化的位点。 试剂优选用于使用质谱的蛋白质组学分析。 抗体试剂特异性结合残留在通过消化或化学处理泛素化蛋白质产生的肽上的泛素(即,赖氨酸的二甘氨酸修饰的ε胺)残基。 本发明的抗体试剂对泛素残留物的亲和力不依赖于修饰(即泛素化)赖氨酸侧翼的剩余氨基酸序列,即它们是上下文无关的。

    • The invention relates to a method for determining the presence of at least one distinct polypeptide in a biological sample comprising contacting the biological sample with a hydrolyzing agent, wherein the hydrolyzing agent is capable of hydrolyzing the distinct polypeptide in a sequence-specific manner such that at least one distinct peptide having a predetermined peptide measured accurate mass would result if the at least one distinct polypeptide were present in the biological sample, to obtain a hydrolyzed sample; bringing the hydrolyzed sample in contact with a substrate comprising at least one immobilized binding partner, wherein the at least one immobilized binding partner is capable of specifically binding the distinct peptide; removing the hydrolyzed sample from the substrate in a manner such that the distinct peptide would remain bound to the immobilized binding partner; contacting the substrate with an elution solution, wherein the distinct peptide would dissociate from the immobilized binding partner into the elution solution; subjecting a portion of the elution solution to liquid chromatography to segregate a plurality of molecules in the portion of the elution solution to obtain sorted molecules; determining the measured accurate mass of at least one sorted molecule present in the elution solution; and determining the presence of the at least one distinct polypeptide in the biological sample when a measured accurate mass of at least one molecule is substantially equal to the predetermined peptide measured accurate mass.
    • 本发明涉及一种用于确定生物样品中至少一种不同多肽的存在的方法,包括使生物样品与水解试剂接触,其中水解试剂能够以序列特异性方式水解不同的多肽, 如果至少一种不同的多肽存在于生物样品中,则得到具有测定精确质量的预定肽的至少一种不同的肽,以获得水解样品; 使水解的样品与包含至少一个固定的结合配偶体的底物接触,其中至少一个固定的结合配偶体能够特异性结合不同的肽; 以使得不同的肽保持与固定的结合配偶体结合的方式从底物中除去水解的样品; 使所述底物与洗脱溶液接触,其中所述不同的肽将从固定的结合配偶体解离成洗脱溶液; 使洗脱溶液的一部分进行液相色谱分离洗脱溶液部分中的多个分子,得到分选的分子; 确定洗脱溶液中存在的至少一种分选分子的测量精确质量; 以及当所测量的至少一个分子的精确质量基本上等于所测量的精确质量的预定肽时,确定生物样品中至少一种不同多肽的存在。
