Abstract: The present invention relates to compounds that are useful as metal ligands and which either contain a molecular recognition moiety or can be bound to a molecular recognition moiety and methods of making these compounds. Once the compounds that contain a molecular recognition moiety are coordinated with a suitable metallic radionuclide, the coordinated compounds are useful as radiopharmaceuticals in the areas of radiotherapy and diagnostic imaging. The invention therefore also relates to methods of diagnosis and therapy utilising the radiolabelled compounds of the invention.

Abstract: The present invention relates to a method of separating one or more immunoglobulin containing proteins from a liquid. The method includes first contacting the liquid with a separation matrix comprising ligands immobilized to a support; allowing the immunoglobulin containing proteins to adsorb to the matrix by interaction with the ligands; followed by an optional step of washing the matrix containing the immunoglobulin containing proteins adsorbed thereon; and recovering said immunoglobulin containing proteins by contacting the matrix with an eluent which releases the proteins. The method improves upon previous separation methods in that each of the ligands comprises one or more of a protein A domain (E, D, A, B, C), or protein Z, or a functional variant thereof, with at least one of the monomers having a substitution of the Asparagine at the position corresponding to N28 of B domain of Protein A or Protein Z, and wherein the ligand provides an increase in elution pH compared to non-substituted ligand.

Abstract: The invention provides a washing method for affinity chromatography in which a wash solution comprising arginine, or an arginine derivative, at pH greater than 8.0, is effective in removing impurities without the presence of a nonbuffering salt, while simultaneously increasing product concentration in the eluate and maintaining a high percent yield of recovered product.

Abstract: The invention discloses a polypeptide capable of binding immunoglobulins or immunoglobulin-containing proteins, which polypeptide comprises six or more domains of protein Z or the C domain of protein A or a functional variant thereof. It also discloses separation matrices comprising the polypeptide and methods of using the separation matrices for separation of immunoglobulins or immunoglobulin-containing proteins.

Abstract: For the removal of high molecular weight compounds from recombinantly produced polypeptides generally chromatographic methods are employed. It has been found that underivatized controlled pore glass (uCPG) selectively binds high molecular weight compounds present in a solution. The purified polypeptide can be recovered e.g. from the flow through of a chromatography column containing uCPG as chromatography material. It has been found that this effect is pronounced at a pH value of about 4 to 6 in buffered solutions. With approximately 100 m2 to 150 m2 uCPG surface per g of polypeptide almost 80% to 95% of the high molecular weight compounds are removed with a yield of 80% to 90% of polypeptide.

Abstract: This disclosure is directed to mixed micelle compositions for administration of e.g., therapeutic agents or imaging agents to a subject.

Abstract: The present invention provides a composition comprising a polymer of a ?-hydroxy short-medium chain fatty acid, which is used for delivering the ?-hydroxy short-medium chain fatty acid or an oligomer thereof to the large intestine. In case the composition is administrated orally, the composition will be delivered to the large intestine, without being degraded in the stomach or short intestine, and degraded by the large intestinal bacterial flora and release the short-medium chain fatty acid or an oligomer thereof. The released short-medium chain fatty acid or an oligomer thereof has useful physiological activities and is effective for treating or preventing inflammatory diseases or cancer in the large intestine.

Abstract: The present invention relates to a method for purifying a protein by separating the protein from impurities in a non-adsorption mode using an activated carbon. In particular, the present invention relates to a method for purifying an antibody using the activated carbon instead of protein A affinity chromatography.

Abstract: Antimicrobial cationic polymers having one or two cationic polycarbonate chains were prepared by organocatalyzed ring opening polymerization. One antimicrobial cationic polymer has a polymer chain consisting essentially of cationic carbonate repeat units linked to one or two end groups. The end groups can comprise a covalently bound form of biologically active compound such as cholesterol. Other antimicrobial cationic polymers have a random copolycarbonate chain comprising a minor mole fraction of hydrophobic repeat units bearing a covalently bound form of a vitamin E and/or vitamin D2. The cationic polymers exhibit high activity and selectivity against Gram-negative and Gram-positive microbes and fungi.
