摘要:
Compositions comprising a cell expressing an AC133 cell surface antigen and an antibody, or antigen binding fragment thereof, that specifically binds to the antigen are provided. Expression of the antigen is highly tissue specific. It is detected on a subset of hematopoietic progenitor and stem cells derived from human bone marrow, fetal bone marrow and liver, cord blood and adult peripheral blood. The subset of cells recognized by AC133 is CD34bright and contains substantially all of the CFU-GM activity present in the CD34+ population. This highly specific distribution of AC133 makes it exceptionally useful as a reagent for isolating and characterizing human hematopoietic progenitor and stem cells. Cells selected for expression of AC133 antigen can be further purified by selection for other hematopoietic stem cell and progenitor cell markers.

A gene, mc1-1, of the bc1-2 family is disclosed along with its nucleotide and amino acid sequence. Also disclosed are diagnostic and therapeutic methods of utilizing the mc1-1 nucleotide and polypeptide sequences.
摘要:
The present invention relates to a method of diagnosis of pathological pregnancy which relies on an evaluation of the amount of placental isoferritin (PLF) in the serum or amniotic fluid of a pregnant woman. Diagnosis may also be achieved by observation of percentages of PLF-bearing lymphocytes in the pregnant female. Detection of PLF levels is achieved by immunoassay with a PLF-specific antibody. Also described is a method of treating or preventing pathological pregnancies and transplant or graft rejection by administration of effective amounts of PLF and/or a PLF-specific antibody in combination with immunization.

The invention provides an agent against HIV and/or related viruses, comprising CD4 or a CD4-like substance and an H2 histone or an H2 histone-like protein. The content of the CD4 or CD4-like substance is preferably less than the antivirally effective dose of that substance alone. The invention also provides an H2 histone or an H2-like protein, for use in a method of medical treatment, in particular against HIV and/or related viruses, and also for use in the manufacture of a pharmaceutical composition against HIV and/or related viruses.
摘要:
A process for preparing nucleoproteic material which comprises immersing organic material into a suitable solvent for a sufficient time to extract nucleoproteins from said material, adding a sufficient amount of an acid to form a precipitate of nucleoproteic material, and recovering said nucleoproteic material precipitate. A composition of nucleoproteic material produced according to this process. A method for alleviating symptoms of neoplastic diseases which comprises sterilizing the composition of nucleoproteic material, preparing a formulation comprising an effective amount of said sterilized composition, and administering said formulation to a patient having symptoms of a neoplastic disease.

摘要:
The present invention relates to the diagnosis of multiple sclerosis. More specifically, this invention relates to an assay for detecting antigen(s) associated with multiple sclerosis. The present invention also relates to the generation of hybridomas which produce monoclonal antibodies which are specific for the multiple sclerosis-associated antigens. The present invention's use is in diagnosing multiple sclerosis and in routine follow-up monitoring of multiple sclerosis patients as to disease progression or response to therapy.
摘要:
Several natural polypeptides (basophil granule proteins, "BGP") derived from the cytoplasmic granules of human basophils, and modified forms thereof, are described. These polypeptides, the DNA which encodes them and antibodies which recognize them, are useful as diagnostics for, and treatments for, pathologies involving inflammatory and IgE-mediated responses, parasitic and helminthic infections, hypersensitivity reactions and certain types of leukocytic leukemias.
