    • Fibrin binding peptides disclosed include (a) peptides having the amino acid sequence of a human Blood Coagulation Factor XIIIA fragment (i.e., NKLIVRRGQSFYVQIDFSRPYDPRRDLFRVEYVIGRYPQENKGTYIPVPIVSELQSGKWGAKIVMREDR SVRLSIQSSPKCIVGKFRMYVAVWTPYGVLRTSRNPETDTYILFNPWCEDDAVYLDNEKEREEYVLNDIGVIFYGEVNDIKTRSWSYGQF-R', where R, is --CONH.sub.2 or --NH.sub.2); (b) peptides which are fragments of the foregoing Factor XIIIA fragment and which retain the capability thereof of binding to fibrin; and (c) peptides which bind to fibrin, which have the amino acid sequence of any of the foregoing peptides, and which have additional amino acid residues attached to the N-terminal end and/or the C-terminal end thereof.The peptides are useful for localizing blood clots in vivo, inhibiting fibrin stabilization, and promoting thrombolysis.
    • 公开的血纤维蛋白结合肽包括(a)具有人血液凝固因子XIIIA片段的氨基酸序列(即,NKLIVRRGQSFYVQIDFSRPYDPRRDLFRVEYVIGRYPQENKGTYIPVPIVSELQSGKWGAKIVMREDR SVRLSIQSSPKCIVGKFRMYVAVWTPYGVLRTSRNPETDTYILFNPWCEDDAVYLDNEKEREEYVLNDIGVIFYGEVNDIKTRSWSYGQF-R”,其中R是-CONH 2或-NH 2)的肽; (b)作为上述因子XIIIA片段的片段并且保留其结合纤维蛋白的能力的肽; 和(c)结合纤维蛋白的肽,其具有任何前述肽的氨基酸序列,并且具有连接到N-末端和/或其C-末端的另外的氨基酸残基。 这些肽可用于体内定位血块,抑制纤维蛋白稳定化和促进溶栓。
