    Abstract: There exist in the art methods of detecting simple peptides. However, methods to determine the effective plasma concentration of mixtures of peptides as a group, rather than for individual peptides with a defined amino acid sequence, are complicated by the heterogeneity of the peptides to be detected. This application provides improved methods of detecting and assessing random sequence polymer (RSP) compositions, methods for the detection and quantitation of RSP compositions, means to determine and enrich a subset of peptides in an RSP composition based on the subset's interactions with certain capture polypeptides, and methods for administering RSP compositions to a subject in need thereof, wherein the dosage regimen and quantity may be determined or evaluated based on the above-mentioned methods for detection and quantitation.

    Abstract: The present invention relates to recombinant blood coagulation factor IX (rFIX) mutants having factor VIII (FVIII) independent factor X (FX) activation potential. Five full length FIX proteins with combinations of mutations of amino acids important for functional activity of FIX and FIX wild type were cloned and expressed in HEK 293 cells. The proteins were tested by an activated partial thromboplastin time (aPTT) assay in FVIII-depleted plasma as well as in FVIII-inhibited patient plasma. In FVIII-depleted plasma functional activity of the FIX mutants was calculated as increased FVIII equivalent activity. The mutant proteins had increased FVIII equivalent activity. In FVIII-inhibited patient plasma the FEIBA equivalent activity was calculated for analysis of FVIII independent FX activation potential. The proteins had also increased FEIBA equivalent activity. Furthermore, the pre-activated FIX proteins had an increased activity in FIX-depleted plasma containing FVIII inhibitors.

  • Patent number: 7939632
    Abstract: The invention relates to therapeutic fusion proteins in which a coagulation factor is fused to a half-life enhancing polypeptide, and in which both are connected by a linker peptide that is proteolytically cleavable. The cleavage of such linkers liberates the coagulation factor from activity-compromising steric hindrance caused by the half-life enhancing polypeptide and thereby allows the generation of fusion proteins may show relatively high molar specific activity when tested in coagulation-related assays. Furthermore, the fact that the linker is cleavable can enhance the rates of inactivation and/or elimination after proteolytic cleavage of the peptide linker compared to the rates measured for corresponding therapeutic fusion proteins linked by the non-cleavable linker having the amino acid sequence GGGGGGV.

  • Publication number: 20100210821
    Abstract: A process for isolation and purification of a target protein by chromatography wherein the chromatography removes or depletes prions (PrPSC), comprising the steps of contacting a potentially PrPSC contaminated sample comprising a target protein with a multimodal chromatographic material; setting buffer conditions so that the target protein is bound to the multimodal chromatographic material and whereas PrPSC is not binding to the multimodal chromatographic material; followed by elution of the target protein. a process for isolation and purification of a target protein free of prion protein (prpSC).
