  • Patent number: 5643881
    Abstract: A protein having potent anti-HIV activity is obtained by a method which comprises culturing a strain of CD4-positive T cells, such as a subclone of CEM cells designated 4084, in a tissue culture medium under conditions in which the cells are induced to produce and secrete a protein having anti-HIV activity, separating the cells from the culture medium containing the protein and then recovering the protein from the medium, wherein the molecular weight of the protein having anti-HIV activity is at least 30,000 daltons as determined by a membrane with defined pore size that retains molecules of 30,000 daltons.
    Type: Grant
    Filed: August 4, 1994
    Date of Patent: July 1, 1997
    Assignee: Tampa Bay Research Institute
    Inventors: Meihan Nonoyama, Akiko Tanaka, Patrick K. Lai
  • Patent number: 5480782
    Abstract: A process for obtaining cellular protein having potent anti-HIV activity comprises culturing CD4-positive T cells or myeloid cells in a tissue culture medium under conditions in which the cells are induced to produce and secrete a protein having anti-HIV activity, separating the cells from the culture medium containing the protein and then recovering the protein from the medium, wherein the molecular weight of the protein having anti-HIV activity, as measured by gel filtration analysis, is within the range of about 7,000 to about 12,000 daltons.
    Type: Grant
    Filed: August 4, 1994
    Date of Patent: January 2, 1996
    Assignee: Tampa Bay Research Institute
    Inventors: Meihan Nonoyama, Akiko Tanaka, Patrick K. Lai
