  • Patent number: 8389687
    Abstract: Blood collection, processing and transfer leads to the separation of discrete fractions by adding additional citrate (trisodium citrate) to bring the citrate concentration to 10%-15% w/v thereby leading to enhanced yield and purity of cryoprecipitate. The improved cryoprecipitate then yields concentrated clotting factors by an improved extraction process which uses polyvinyl pyrollidone to reduce the extraction of fibrinogen. Following extraction the remaining cryoprecipitate can advantageously be formed into a fibrin fabric used in surgeries and in the treatment of wounds.

  • Patent number: 8388847
    Abstract: The invention relates generally to methods of concentrating mixtures including shear sensitive biopolymers, such as von Willebrand Factor. Conventional methods of concentrating biopolymers impart too much shear stress, which causes the degradation of shear sensitive biopolymers. The methods disclosed herein reduce the shear stress while maintaining a high rate of filtrate flux. Disclosed herein is a method for concentrating shear sensitive biopolymers including flowing a mixture with a shear sensitive biopolymer into a hollow fiber dialysis module to form a retentate having a shear sensitive biopolymer concentration that is greater than that of the mixture. Hollow fiber dialysis modules have high filtrate fluxes and low shear rates at low flow rates. This ensures a high product yield and minimal loss of shear sensitive biopolymers.

  • Publication number: 20120297494
    Abstract: It has been determined that most mutations in factor VIII occur in multiple haplotypes, not primarily in one haplo-type. The frequencies of mild, moderate, and severe hemophilia did not differ significantly according to the background haplo-type. The odds of having inhibitor were significantly higher among patients in the H3+H4 haplotype groups as compared to H1+H2 haplotype groups. This association appears to be independent of the mutation. The results indicate that white hemophiliacs should be treated with Kogenate®. However, it would clearly be of benefit to assess the haplotype of black hemophiliacs prior to prescribing the recombinant FVIII to be used for treatment. It is not essential to determine the actual mutations responsible for the hemophilia prior to prescribing the recombinant FVIII. Also described are transgenic human FVIII animal models.

  • Publication number: 20120190623
    Abstract: The present invention provides novel purified and isolated nucleic acid sequences encoding procoagulant-active FVIII proteins. The nucleic acid sequences of the present invention encode amino acid sequences corresponding to known human FVIII sequences, wherein residue Phe309 is mutated. The nucleic acid sequences of the present invention also encode amino acid sequences corresponding to known human FVIII sequences, wherein the APC cleavage sites, Arg336 and Ile562, are mutated. The nucleic acid sequences of the present invention further encode amino acid sequences corresponding to known human FVIII sequences, wherein the B-domain is deleted, the von Willebrand factor binding site is deleted, a thrombin cleavage site is mutated, an amino acid sequence spacer is inserted between the A2- and A3-domains.

  • Publication number: 20120178139
    Abstract: Peptides that specifically bind erythrocytes are described. These are provided as peptidic ligands having sequences that specifically bind, or as antibodies or fragments thereof that provide specific binding, to erythrocytes. The peptides may be prepared as molecular fusions with therapeutic agents, tolerizing antigens, or targeting peptides. Immunotolerance may be created by use of the fusions and choice of an antigen on a substance for which tolerance is desired.

  • Publication number: 20120149874
    Abstract: The present disclosure relates to a method for preparing recombinant glycoproteins with high sialic acid content. More specifically, for UDP-GlcNAc 2-epimerase/ManNAc kinase (GNE/MNK) enzyme where point mutation was induced by substituting arginine at position 263 by leucine only or by further substituting arginine at position 266 by glutamine, epimerase activity is constantly maintained, and overexpressed cells thereof experience an increase in intracellular cytidine monophosphate (CMP)-sialic acid content, irrespective of CMP-sialic acid concentration.
