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.
