title: Production of high titre human interferon-gamma in primed leukocyte cultures.
abstract: Con A-stimulated leukocytes previously treated with IFN-alpha (1500 IU/ml for 4 h) were very suitable for the production of IFN-gamma with a high titre even under large-scale conditions. The properties of the IFN produced under such conditions were identical to those of IFN-gamma. The IFN-gamma produced in primed cultures showed two peaks of antiviral activity corresponding to molecular weights of 51 000 and 23 000 daltons.
