  • Publication number: 20080076712
    Abstract: Methods are described for preventing or reducing ischemia and/or systemic inflammatory response in a patient such as perioperative blood loss and/or systemic inflammatory response in a patient subjected to cardiothoracic surgery, e.g. coronary artery bypass grafting and other surgical procedures, especially when such procedures involve extra-corporeal circulation, such as cardiopulmonary bypass.

  • Publication number: 20070259417
    Abstract: In order to obtain a novel binding protein against a chosen target, DNA molecules, each encoding a protein comprising one of a family of similar potential binding domains and a structural signal calling for the display of the protein on the outer surface of a chosen bacterial cell, bacterial spore or phage (genetic package) are introduced into a genetic package. The protein is expressed and the potential binding domain is displayed on the outer surface of the package. The cells or viruses bearing the binding domains which recognize the target molecule are isolated and amplified. The successful binding domains are then characterized. One or more of these successful binding domains is used as a model for the design of a new family of potential binding domains, and the process is repeated until a novel binding domain having a desired affinity for the target molecule is obtained.

  • Publication number: 20070041959
    Abstract: Disclosed are compounds that comprise: (i) a Kunitz domain polypeptide that comprises a Kunitz domain that binds to and inhibits a protease; and (ii) a plurality of polyethylene glycol moieties attached to the Kunitz domain polypeptide. Each accessible primary amine of the Kunitz domain polypeptide can be attached to one of the moieties. Also disclosed are related methods.

  • Publication number: 20070031879
    Abstract: Novel enterokinase cleavage sequences are provided. Also disclosed are methods for the rapid isolation of a protein of interest present in a fusion protein construct including a novel enterokinase cleavage sequence of the present invention and a ligand recognition sequence for capturing the fusion construct on a solid substrate. Preferred embodiments of the present invention show rates of cleavage up to thirty times that of the known enterokinase cleavage substrate (Asp)4-Lys-Ile.

  • Publication number: 20050222023
    Abstract: The invention relates to proteins comprising serine protease inhibiting peptides, such as Kunitz domain peptides (including, but not limited to, fragments and variants thereof) fused to albumin, or fragments or variants thereof. These fusion proteins are herein collectively referred to as “albumin fusion proteins of the invention.” These fusion proteins exhibit extended shelf-life and/or extended or therapeutic activity in solution. The invention encompasses, therapeutic albumin fusion proteins, compositions, pharmaceutical compositions, formulations and kits. The invention also encompasses nucleic acid molecules encoding the albumin fusion proteins of the invention, as well as vectors containing these nucleic acids, host cells transformed with these nucleic acids and vectors, and methods of making the albumin fusion proteins of the invention using these nucleic acids, vectors, and/or host cells.
