Annales Immunologiae Hungaricae
|January 1, 1975
Enhancing factor was prepared from spleens of mice primed and reinjected with tetanus toxoid. The culture supernatant was separated by gel chromatography on Sephadex G-150, the resulted fractions were ultrafiltered and their enhancing activity was tested in vivo. The 1st fraction separated by gel chromatography proved to be active.
