Definitions

  • a vector suitable for use herein for the production of a recombinant vector comprises a nucleic acid sequence with one or more restriction enzyme recognition sites into which the present nucleic acid molecule of the invention can be inserted. This vector also typically contains a selection marker for detection of the presence of the vector in the host cell.
  • promoters useful for expression of eukaryotic proteins are also suitable.
  • a person skilled in the art would be able to operably ligate such promoters to the present Factor VIILC polypeptide analog coding sequences, for example, as described in Siebenlist et al, Cell (1980) 20: 269, using linkers or adapters to supply any required restriction sites.
  • Promoters for use in bacterial systems also generally will contain a Shine-Dalgarno (SD) sequence operably linked to the DNA encoding the Factor VIILC analog polypeptide.
  • SD Shine-Dalgarno
  • Methods of introducing exogenous DNA into yeast hosts are well known in the art, and typically include either the transformation of spheroplasts or of intact yeast cells treated with alkali cations. Transformations into yeast can be carried out according to the method described in Van Solingen et al. , J. Bact. (1977) 130: 946 and Hsiao et aL , Proc. Natl. Acad. Sci. USA (1979) 76: 3829. However, other methods for introducing DNA into cells such as by nuclear injection, electroporation, or protoplast fusion may also be used as described generally in Sambrook et al. , cited above.
  • gene expression from the polyhedrin promoter occurs at a time when the host cell's ability to process newly synthesized proteins is potentially diminished for certain proteins such as human tissue plasminogen activator.
  • the expression of secretory glycoproteins in BEV systems is complicated due to incomplete secretion of the cloned gene product, thereby trapping the cloned gene product within the cell in an incompletely processed form.
  • the desired DNA sequence can be inserted into the transfer vector, using known techniques.
  • An insect cell host can be cotransformed with the transfer vector containing the inserted desired DNA together with the genomic DNA of wild type baculovirus, usually by cotransfection.
  • the vector and viral genome are allowed to recombine resulting in a recombinant virus that can be easily identified and purified.
  • the packaged recombinant virus can be used to infect insect host cells to express a Factor VIILC polypeptide analog.
  • the recombinant virus can then be isolated and delivered to cells of the subject either in vivo or ex vivo.
  • retroviral systems have been described (U.S. Patent No. 5,219,740; Miller and Rosman, BioTechniques (1989) 7:980-990; Miller, A.D., Human Gene Therapy (1990) 7:5-14; Sca ⁇ a et aL , Virology (1991) 780:849-852; Burns et aL , Proc. Natl. Acad. Sci. USA (1993) 90:8033-8037; and Boris-Lawrie and Temin, Cur. Opin. Genet. Develop. (1993) 3: 102-109.
  • an avipox vector is particularly desirable in human and other mammalian species since members of the avipox genus can only productively replicate in susceptible avian species and therefore are not infective in mammalian cells.
  • Methods for producing recombinant avipoxviruses are known in the art and employ genetic recombination, as described above with respect to the production of vaccinia viruses. See, e.g. , WO 91/12882; WO 89/03429; and WO 92/03545.
  • a medium sample containing wild type heavy and light chains with a total of 37 mU of coagulation activity was incubated in a volume of 200 ⁇ l in 20 M imidazole, 150 mM NaCl, 2.5 mM CaCl 2 , 100 mM lysine HCl, pH 6.8 at 4°C.
  • the reaction was started at time 0 by the addition of either 25 mU of thrombin or buffer alone and transferred to room temperature. Samples were removed at selected times and immediately assayed for coagulation activity. The same experiment was also performed on medium containing the wild type 92 chain and the mutant 80R ⁇ K chain.
  • the 80 ⁇ R, 92 ⁇ R and 92R ⁇ K species were essentially not thrombin activatable under the assay conditions. However the 80R ⁇ K peptide was thrombin activatable to the same extent as the wild type chain although at a slower rate.
