    Inventor: Giulio Ratti
  • Synthetic peptide endowed with immunological activity, capable of inducing the production of antibodies with a high specificity towards alpha-fetoprotein, and their use in the diagnostic field
    Patent number: 5130415
    Abstract: A synthetic peptide endowed with immunological activity is disclosed, which is capable of inducing in mammals the formation of anti-peptide antibodies capable of recognizing human alpha-fetoprotein and of reacting with it, and incapable of recognizing albumin or its degradation products, with said peptide being essentially constituted by the aminoacidic sequence of formula (I), corresponding to 38-119 region of human alpha-fetoprotein.Furthermore, the methods and means for preparing said peptide by means of the recombinant DNA techniques are reported.The synthetic peptide (I), like the polyclonal and monoclonal antipeptide antibodies are particularly suitable for the early diagnosis of hepatocellular carcinoma and of teratocarcinoma.
    Type: Grant
    Filed: July 24, 1989
    Date of Patent: July 14, 1992
    Assignee: Sclavo S.p.A.
    Inventors: Mario F. Tecce, Marzia M. Giuliani, Stefano Ricci, Giulio Ratti, Benedetto Terrana
  • Biologically active material
    Patent number: 3975520
    Abstract: Purified polyhedral virus particles capable of stimulating the production of interferon in animals are obtained from the fungal cells of the mold Aspergillus foetidus or Aspergillus niger or from the nutrient medium in which or on which said molds have been grown.
    Type: Grant
    Filed: July 10, 1974
    Date of Patent: August 17, 1976
    Assignee: Beecham Group Limited
    Inventors: Ernst Boris Chain, Kenneth William Buck, Joan Elizabeth Darbyshire, Geoffrey Talbot Banks, Fred Himmelweit, Giulio Ratti
  • Process for preparing double stranded RNA
    Patent number: 3966707
    Abstract: Virus particles capable of stimulating the production of interferon are isolated from fungal cells of the mould Aspergillus foetidus or Aspergillus niger or from the nutrient medium in which or on which Aspergillus foetidus or Aspergillus niger mould has been grown. Double-stranded RNA material can be isolated from the virus particles extracted from Aspergillus foetidus or Aspergillus niger and said RNA material is capable of stimulating production of interferon. Pharmaceutical compositions comprising said particles or said RNA material in combination with pharmaceutically acceptable carriers and excipients are also provided.
