Also disclosed are diagnostic and immunotherapeutic methods of using the monoclonal antibodies as well as cell lines producing the monoclonal antibodies.

Abstract: The present invention includes methods and compositions for treating humans and other animals intoxicated with at least one clostridial toxin by administration of antitoxin. In particular, the antitoxin directed against these toxins is produced in avian species. This avian antitoxin is designed so as to be orally administerable in therapeutic amounts and may be in any form (i.e., as a solid or in aqueous solution).

Abstract: Disclosed is a method of inhibiting a rejection response by a primate to a transplanted organ. One exposes the primate to a mutant diphtheria toxin linked to anti-CD3 antibody so as to largely eliminate the host's peripheral blood T cell lymphocyte population. At the same time as, or after, the exposure step one administers to the primate's thymus gland donor lymphocytes. Transplantation of the organ follows. The primate is tolerized to the transplanted organ.

Antigen-binding fusion proteins having phospholipase A activating protein and/or tumor necrosis factor fragments are also provided by the invention. Genetic sequences coding for single-chain and multivalent immunoeffector antigen-binding fusion proteins are disclosed.

Abstract: A method for the selective depletion of activated CD4.sup.+ T-cells in vivo by using immunotoxins comprising the OX-40 antibody conjugated to a toxic molecule (such as Ricin-A chain). The administration of these specific immunotoxins is used therapeutically to deplete autoimmune reactive CD4.sup.+ T-cells which have been implicated in diseases including Multiple Sclerosis, Rheumatoid Arthritis, Sarcoidosis, and Autoimmune Uveitis. This type of therapy is also beneficial for eradicating CD4.sup.+ T-cell lymphomas and alloreactive CD4.sup.+ T-cells involved with a transplantation reaction. The use of the human form of the OX-40 antibody will also help in the early diagnosis of all the diseases mentioned above.

Abstract: There is provided an isolated immunoglobulin comprising two heavy polypeptide chains sufficient for the formation of a complete antigen binding site or several antigen binding sites, wherein the immunoglobulin is further devoid of light polypeptide chains.

Abstract: The present invention relates to monoclonal antibodies that are distinguished by a high degree of selectivity and affinity towards herbicides from the group of the sulfonylureas, especially towards sulfonylurea herbicides of formula (A) ##STR1## wherein X is a mono- or di-substituted 6-membered heterocycle having from one to three nitrogen atoms and bonded via carbon, but is preferably mono- or di-substituted s-triazine or pyrimidine; andn is an integer from 0 to 4, preferably the number 1, and that are therefore outstandingly suitable for use in an immunoassay for the rapid and effective detection of the said sulfonylurea herbicides in soil, water or air samples or in plant extracts, and to methods for the production of said monoclonal antibodies. The present invention relates also to hybridoma cell lines that produce said monoclonal antibodies and to immunological detection methods using said monoclonal antibodies, and to test kits that may be used in those detection methods.

Abstract: The present invention provides purified and isolated polynucleotides encoding Type I ribosome-inactivating proteins (RIPs) and analogs of the RIPs having a cysteine available for disulfide bonding to targeting molecules. Vectors comprising the polynucleotides and host cells transformed with the vectors are also provided. The RIPs and RIP analogs are particularly suited for use as components of cytotoxic therapeutic agents of the invention which include gene fusion products and immunoconjugates. Cytotoxic therapeutic agents or immunotoxins according to the present invention may be used to selectively eliminate any cell type to which the RIP component is targeted by the specific binding capacity of the second component of the agent, and are suited for treatment of diseases where the elimination of a particular cell type is a goal, such as autoimmune disease, cancer and graft-versus-host disease.

Abstract: Egg yolks and egg yolk fractions containing effective therapeutic concentrations of avian antibodies against parasitic antigen, and a method of providing passive immunization for the prevention or treatment of intestinal parasitosis by enteral administration of egg yolk antibodies harvested from hyperimmunized avian hens. Also provided are pharmaceutical formulations comprising the egg yolk antibodies.

Abstract: Disclosed is a formulation for targeting an epitope on an antigen expressed in a mammal. The formulation comprises a pharmaceutically acceptable carrier together with a dimeric biosynthetic construct for binding at least one preselected antigen. The biosynthetic construct contains two polypeptide chains, each of which define single-chain Fv (sFv) binding proteins and have C-terminal tails that facilitate the crosslinking of two sFv polypeptides. The resulting dimeric constructs have a conformation permitting binding of a preselected antigen by the binding site of each polypeptide chain when administered to a mammal. The formulation has particular utility in in vivo imaging and drug targeting experiments.
