  • Patent number: 5864019
    Abstract: A multivalent antigen-binding protein comprises a first Fv fragment bound to at least one further Fv fragment by a connecting structure which links the Fv fragments to each other but which maintains them spaced apart such that the proteins are capable of binding to adjacent antigenic determinants. Typically the connecting structure comprises a spacing polypeptide sequence, which may be about 3 to 16 amino acids in length, connected to a linkage unit which may be a synthetic chemical linker, e.g., a maleimide linker, or is a polypeptide sequence leading from the spacing sequence. In a particularly preferred embodiment, the multivalent antigen binding protein comprises a VH domain having attached to its C-terminal end a V-C joining sequence and an antibody hinge sequence. Preferably one or more of the Fv fragments is a single chain Fv (scFv). The proteins are preferably prepared by recombinant DNA techniques and are useful for in vivo therapeutic and especially diagnostic applications.

  • Patent number: 5859213
    Abstract: A method for preparing an aqueous protein composition from human blood plasma, wherein the plasma undergoes a series of treatments by heating and precipitating agent to give albumin solutions containing the precipitating agent, and said precipitating agent is separated from the resulting solutions to give a crude aqueous albumin solution which is subjected to at least one liquid phase chromatography step to retain at least part of the secondary proteins other than albumin. The chromatography comprises affinity chromatography on a particulate support consisting of neutral particles loaded with at least one compound comprising sulphate groups, whereby, after the albumin solution has been fed through, the particulate affinity chromatography support is eluted by feeding through an aqueous saline solution, preferably by increasing the ionic strength, and the desired protein composition is collected by elution.

  • Patent number: 5854417
    Abstract: Borna disease virus (BDV) causes a rare neurological disease in horses and sheep. A subtractive cDNA expression library was constructed with poly A-selected RNA from a BDV Infected MDCK cell line. A clone (B8) was isolated that specifically hybridizes to RNA isolated from BDV-infected brain tissue and BDV-infected cell lines. This clone hybridizes to four BDV-specific positive strand RNAs and one negative strand RNA in BDV-infected rat brain. Nucleotide sequence analysis of the clone suggests that it represents a full length mRNA which contains several open reading frames. The Borna Disease Virus DNA sequences as well as proteins encoded by the BDV DNA sequences are provided.

  • Patent number: 5851527
    Abstract: The targeting capability of an antibody is enhanced using an antibody-enzyme conjugate and a separate soluble substrate-agent conjugate, wherein the targeted enzyme catalyzes the conversion of a soluble substrate, bearing at least one therapeutic or diagnostic agent, to a product comprising the agent, which accumulates at the target site for effective treatment or diagnosis. This method is useful for targeting any type of agent to a site to which an antibody can selectively bind, including use for imaging, e.g., tumors, infectious lesions, fibrin clots, myocardial infarctions, non-cancerous cells, damaged normal cells, atherosclerotic plaque, lymphocyte autoreactive clones, and for therapy, e.g., with drugs, toxins, immune modulators, radioisotopes or antibiotics.
