| 摘要 |
DNA sequences that code for proteins having substantially the same biological activity as Factor XIII are disclosed. DNA sequence coding for polypeptides that are functionally homologous to the a, a', and b subunits of Factor XIII are contained within expression vectors useful for transfecting a variety of eucaryotic and procaryotic host cells. Methods for preparing (a) proteins having substantially the same biological activity as Factor XIII; (b) proteins which, upon dissociation in the presence of calcium, have substantially the same biological activity as Factor XIIIa; (c) proteins which, upon actuation, have substantially the same biological activity as Factor XIIIa; and (d) methods for preparing proteins which have substantially the same biological activity of Factor XIIIa are also disclosed. |
