Abstract: Processes for conjugating proteins with polyethylene glycol are disclosed. The disclosed processes provide modified proteins having little or no decrease in their activity and include the steps of deleting at least one amino acid residue on the protein, replacing the at least one amino acid residue with an amino acid residue that does not react with polyethylene glycol, and contacting the protein with polyethylene glycol under conditions sufficient to conjugate the polyethylene glycol to the protein. This advantageous retention of a desired protein activity is attributed to the availability of one or more protein binding sites which is unaltered in the conjugation process and thus remains free to interact with a binding partner ligand or cognate subsequent to the conjugation process.
Abstract: The invention provides methods of treating autoimmune and chronic inflammatory conditions by administering agents that hinder the CD30/CD30L interaction, combination treatments, and methods of treating conditions resistant to treatment with TNF? inhibitors by administering agents that inhibit signal transduction by CD30 or IL-1. Included also are treatments involving concurrently administering agents that block the CD30/CD30L interaction and agents that antagonize the IL-4/IL-4R interaction. Additionally provided is an animal model for screening candidate agents for their efficacy in treating conditions that are resistant to treatment with TNF? inhibitors.

Abstract: A method is provided for separating a protein from one or more other proteins using hydroxyapatite chromatography in which the protein does not bind to hydroxyapatite but the other protein(s) does. In some embodiments, a second protein affixed to a solid support has been used previously to purify the protein by affinity chromatography, and small amounts of the second protein are introduced in the sample during this process. The protein being purified can comprise at least one constant antibody immunoglobulin domain. The second protein can bind to proteins comprising such a domain.

Abstract: The present invention provides polypeptide purification reagents that are, themselves, proteins and methods for using these to purify almost any protein of interest. A polypeptide purification reagent comprises a polypeptide domain that can bind to a protein of interest and a polypeptide domain that confers a propensity to precipitate under conditions where the vast majority of proteins will not precipitate. In addition or as an alternative, a polypeptide purification reagent can comprise amino acid sequences that confer an ability to partition into a phase in a liquid—liquid phase system that the majority of proteins do not partition into. Methods for purifying a protein of interest using such polypeptide purification reagents are also provided.
Abstract: This invention relates to B7-H3A, a new member of the human B7 polypeptide family, methods of making such polypeptides, and to methods of using them to treat immunological conditions and to identify compounds that alter B7-H3A polypeptide activities.
