    • The present invention relates to specific substrates for a von Willebrand factor cleaving enzyme, ADAMTS-13, as well as to diagnosis of ADAMTS-13 deficient patients, diagnostic compositions, and kits employing the substrates. Particularly preferable substrate polypeptides for ADAMTS-13 are the polypeptide which begins at amino acid 1587 and ends at amino acid 1668 of SEQ ID NO: 1 in the Sequence Listing, and the polypeptide which begins at amino acid 1596 and ends at amino acid 1668 of SEQ ID NO: 1 in the Sequence Listing. These substrate polypeptides for ADAMTS-13 have high substrate specificity and also superior quantitativeness, and a suitable size for production by recombinant methods.
    • 本发明涉及von Willebrand因子切割酶,ADAMTS-13的特异性底物,以及ADAMTS-13缺陷患者的诊断,诊断组合物和使用该底物的试剂盒。 用于ADAMTS-13的特别优选的底物多肽是从序列表中SEQ ID NO:1的氨基酸1587开始并结束于SEQ ID NO:1的氨基酸1668的多肽,以及在氨基酸1596开始并以氨基酸1668结束的多肽 序列表中的SEQ ID NO:1。 用于ADAMTS-13的这些底物多肽具有高底物特异性,并且还具有优异的定量性,以及通过重组方法生产的合适尺寸。
