Abstract:
Novels peptides and pharmaceutical compositions comprising the same are disclosed. Conjugated compositions peptides linked to detectable agents and/or cytotoxic agents. are disclosed. Method of detecting tumors that have p185 on tumor cell surfaces are disclosed. Methods of preventing transformation of a normal cell into a tumor cell in an individual at risk of developing a tumor having tumor cells which have p185 on their surfaces are disclosed. Methods of treating an individual who has cancer characterized by tumor cells that have a p185 on their cell surfaces are disclosed.
Abstract:
Methods, systems and kits are provided for detecting molecules expressing a selected epitope in a sample through use of an epitope detector containing a single chain Fv for the selected epitope or a constrained epitope specific CDR attached to an oligonucleotide.

Abstract:
Constrained peptides are disclosed which have cyclic portions that contain biologically active regions linked to two linear extensions that each comprise at least one aromatic-group containing amino acid residue. The constrained peptides of the invention are biologically active.
Abstract:
Methods of enhancing epithelial cell proliferation are disclosed. The methods comprise the step of contacting epithelial cells with a compound that binds to reovirus type 3 receptor. Methods of treating an individual susceptible to or suffering from a condition, disease or disorder characterized by insufficient proliferation of epithelial cells are disclosed. The methods comprise the steps of identifying such individuals and administering to them a therapeutically effect amount of compound that binds to reovirus type 3 receptor and thereby enhances proliferation of epithelial cells. Methods of treating individuals suffering from wounds that involve epithelial cells are disclosed. The methods comprise the steps of identifying such individuals and administering to them a therapeutically effect amount of compound that binds to reovirus type 3 receptor and thereby enhances proliferation of epithelial cells.
Abstract:
A substantially purified saccular collagen protein and compositions, including pharmaceutical compositions, that comprise the saccular collagen protein are disclosed. Methods of using the saccular collagen which comprise injecting the saccular collagen into the tissue of an individual are disclosed. Antibodies which bind to the saccular collagen protein, nucleic acid molecules which encode the saccular collagen protein, and oligonucleotides which are identical or complementary to at least a portion of the sequence that encodes the saccular collagen proteins are disclosed. Recombinant expression vector that comprise nucleic acid molecules that encode the saccular collagen protein and host cells, including the cells of transgenic animals, which comprise the recombinant expression vectors are disclosed.
Abstract:
A purified proteinaceous substance bindable with p185, the translation product of the neu oncogene is disclosed. The purified proteinaceous substance may be characterized in that it increases the activity of the tyrosine kinase contained in the neu oncogene product but does not increase the activity of tyrosine kinase of epidermal growth factor receptor; induces p185 dimerization and internalization; affects the growth of cells which express p185 in a dose dependent manner; is heat stable from about 56.degree. C. to about 100.degree. C.; is degradable by protease; and has a molecular weight of from about 7,000 to about 14,000 daltons in its smallest active form as determined by gel filtration and ultrafiltration membrane analysis. Methods of detecting p185 on the surfaces of tumor cells are also disclosed.
Abstract:
Compositions which are immunologically crossreactive with antibodies are provided, together with preparative and therapeutic methods therefor. The compositions preferably comprise a plurality of covalently bound synthetic compounds, at least one of which is individually crossreactive with at least one complementarity determining region (CDR) of the antibody. Preferred processes for preparing the immunologically crossreactive compounds comprise identifying chemical functionality such as hydroxyl groups in the CDR which participates in at least one immunological binding phenomena, determining the three-dimensional positioning of the chemical functionality, and synthesizing a compound which comprises substantially the same chemical functionality as the CDR and which has at least one conformation wherein the three-dimensional positioning of the chemical functionality is substantially identical to the three-dimensional positioning of the chemical functionality of the CDR.
Abstract:
The present invention provides methods for treating mammalian diseases and conditions characterized by myelin destruction. The present invention provides methods for inducing myelin formation by myelin forming cells expressing reovirus type 3 receptors comprising administering to such cells an effective amount of a compound bindable with the reovirus type 3 receptor. The compounds for use in the method of the invention preferably comprise antibodies and peptides, more preferably synthetic peptides.
Abstract:
Mammals are vaccinated against infectious organisms and polypeptides are screened for utility as vaccines by a complementing set of monoclonal antibodies, the first of which antibodies binds specifically to the site on the organism which itself binds specifically to a receptor on a host cell of the mammal, and the second of which binds specifically to the first. Vaccination is done with the second antibody alone, and screening is done by determining whether the polypeptide binds to the first antibody.
