  • Human B-cell differentiation factor and process of producing said factor
    Patent number: 5530098
    Abstract: A cDNA and a chromosomal DNA coding for the human B-cell differentiation factor were provided and the entire nucleotide sequence of said DNAs as well as the entire amino acid sequences of the polypeptide portion of mature human B-cell differentiation factor and the leader peptide were revealed. The method for producing human B-cell differentiation factor by a recombinant gene technology was also provided.
    Type: Grant
    Filed: June 8, 1994
    Date of Patent: June 25, 1996
    Assignee: Suntory Limited
    Inventors: Tasuku Honjo, Kiyoshi Takatsu, Eva Severinson
  • DNAs that code for mouse interleuken 4
    Patent number: 5416201
    Abstract: Mouse IgG.sub.1 inducing factor and the DNA that codes for the same were isolated by using a novel genetic technique, and their structures determined by the dideoxy chain termination method. The mouse IgG.sub.1 inducing factor obtained by the method of this invention has activity to improve immune response in living bodies and are hence useful for the treatment and prevention of infectious diseases, AIDS, functional immunodeficiency and the like. This factor, or part of its amino acid sequence, may also be used for the preparation of antibody against the same. In addition, it is possible to use this factor as a model for the synthesis of other polypeptides having similar structures, and for many other purposes.
