  • Patent number: 6265150
    Abstract: Peripheral blood leucocytes incubated with a semi-synthetic phage antibody library and fluorochrome-labeled CD3 and CD20 antibodies were used to isolate human single chain Fv antibodies specific for subsets of blood leucocytes by flow cytometry. Isolated phage antibodies showed exclusive binding to the subpopulation used for selection or displayed additional binding to a restricted population of other cells in the mixture. At least two phage antibodies appeared to display hithereto unknown staining patterns of B lineage cells. This approach provides a subtractive procedure to rapidly obtain human antibodies against known and novel surface antigens in their native configuration, expressed on phenotypically defined subpopulations of cells. Importantly, this approach does not depend on immunization procedures or the necessity to repeatedly construct phage antibody libraries.

An antibody which binds to an 80 kDa surface protein on the maternal surface of normal term human syncytiotrophoblast (R80K) was discovered. This antibody was also found to bind to Natural Killer (NK) target cells (K562) and inhibit NK killing of this human NK target cell line. A monoclonal antibody (BA11) was raised against K562 cells which was also directed against a monomorphic site on the R80K surface protein of placentae.

Only select subpopulations of Mac-1 molecules are activated and become capable of binding ligand. Further, the activated Mac-1 molecules were found to possess activation specific epitopes which distinguishes them from non-activated Mac-1 molecules. Based on these observations antibodies are described which selectively bind activated Mac-1 molecules but are substantially incapable of binding non-activated Mac-1.

These factors are useful for the treatment of neural tumors. Also disclosed are the DNA sequences encoding novel polypeptides which may have use as agents which inhibit cell proliferation. Methods for the synthesis, purification, and testing of both known and novel polypeptides for their use as therapeutic and diagnostic aids in the treatment of diseases are also provided. Methods are also provided for the use of these polypeptides for the preparation of antibody probes. Such probes have diagnostic and therapeutic use in diseases involving neural and glial cells.

  • Patent number: 5874255
    Abstract: Chimeric human antibody expression vectors are constructed by inserting the antibody heavy chain variable region-encoding cDNA and antibody light chain variable region-encoding cDNA isolated from hybridomas producing a mouse or rat monoclonal antibody reacting with the ganglioside GM.sub.2 respectively into an expression vector for use in animal cells which contains the human antibody heavy chain constant region- or human antibody light chain constant region-encoding cDNA. The expression vectors are introduced into animal cells and the transformant thus obtained is cultured for the production of a chimeric human antibody reacting with the ganglioside GM.sub.2.

  • Patent number: 5866689
    Abstract: Monoclonal antibodies recognizing gp130 protein and binding to the protein to inhibit IL-6 functions completely (that is to the same level as that is the absence of IL-6) when present in enough amount; a hybridoma producing the monoclonal antibody; a process for production of the monoclonal antibodies using the hybridoma; and an inhibitory agent for inhibition of physiological actions of IL-6 comprising the monoclonal antibodies.

  • Patent number: 5856135
    Abstract: A reshaped antibody comprising:(A) L chains comprising:(1) a human C region, and(2) an L chain V region comprising human L chain FRs and L chain CDRs of a mouse monoclonal antibody; and(B) H chains comprising:(1) a human H chain C region, and(2) an H chain V region comprising human H chain FRs, and H chain cDRs of a mouse monoclonal antibody to human IL-6. Since the major portions of the reshaped human antibody are derived from human, and the mouse CDRs are less immunogenic, then the present reshaped human antibody is less immunogenic, and therefore inhibits information transfer by IL-6, and is promising as a therapeutic agent for diseases caused by IL-6.

  • Patent number: 5843674
    Abstract: A mammal is immunized by using an antigen of a peptide having an amino acid sequence existing in a region having low homology to amino acid sequences of tyrosinase-related proteins but included in an amino acid sequence of human tyrosinase, and then the spleen cells of the mammal is fused with cultured cells to prepare a hybridoma producing monoclonal antibody which binds to human tyrosinase and mouse tyrosinase but does not bind to the tyrosinase-related proteins.
