[Use of filter-adsorbed enterotoxins for isolating human immune interferon].

The use of A and B enterotoxins of St. aureus adsorbed on Millipore nitrocellulose filters for induction of donor blood leukocytes resulted in production of immune interferon free of the inducer. The interferon produced by this method is acid-labile and inactivated by antiserum to human immune interferon but not to human leukocyte interferon. The advantage of this type of induction consists in the possibility of multiple use of the filters with adsorbed enterotoxins.
