  • Publication number: 20150273114
    Abstract: The present invention relates to hydrogels comprising a plurality of amphiphilic peptides and/or peptoids capable of self-assembling into three-dimensional macromolecular nanofibrous networks, which entrap water and form said hydrogels, wherein at least a portion of said plurality of amphiphilic peptides and/or peptoids is chemically cross-linked. The present invention further relates to methods for preparing such hydrogels and to various uses of such hydrogels, e.g. as cell culture substrates, for drug and gene delivery, as wound dressing, as an implant, as an injectable agent that gels in situ, in pharmaceutical or cosmetic compositions, in regenerative medicine, in tissue engineering and tissue regeneration, or in electronic devices.

  • Publication number: 20100099113
    Abstract: The present invention relates to the composition of small molecules and their use in the field of protein isolation, purification, stabilizing and/or enhancing its activity. In particular, the present invention relates to the synthesis and optimization of compounds comprising small peptides and peptide derivatives with affinity to coagulation Factor VIII and/or Factor VIII-like polypeptides and/or domains thereof. These compounds are useful for labeling, detecting, identifying, isolating and preferably for purifying, stabilizing and enhancing the activity of Factor VIII, Factor VIII-like polypeptides or domains thereof from physiological and non-physiological solutions comprising same. Further, these compounds may be used as ligands, which bind Factor VIII, Factor VIII-like polypeptides or domains thereof in methods of the present invention.

  • Publication number: 20090215025
    Abstract: The present invention pertains to compounds that show a high affinity to Factor VIII and Factor VIII-like proteins, and their uses. The compounds are characterized by the general Formula B-Q-X, wherein B represents a dipeptide, tripeptide, or a peptidomimetic; Q represents a spacer and X represents an anchoring molecule; Q and X are optional. These compounds can be used for coating a solid support material. The resulting coated solid support material can be used for purifying Factor VIII by means of affinity chromatography methods. In addition, the compounds of the present invention may be used for stabilizing Factor VIII and for enhancing its activity. The present invention thus pertains also to methods for manufacturing a stabilized Factor VIII containing medicament of increased activity. The inventive compounds can furthermore be used in diagnostic kits and as research tools.

  • Patent number: 7572619
    Abstract: The present invention relates to an improved method for the production of recombinant human blood clotting factors, in particular of factor VIII and factor IX. An immortalized human cell line can be used to stably express viral transcription activator proteins and carrying a vector having a promoter functionally linked to a DNA sequence coding for a blood coagulating factor, provided that said promoter is not a viral promoter which is stimulated by said viral transcription activator proteins. The invention further relates to an immortalized human cell line carrying said vector, factor VIII muteins particularly suitable for the above production method; pharmaceutical compositions comprising such factor VIII muteins, and the use of such factor VIII muteins for preparing a medicament for treating hemophilia.
