An enzyme which converts radical oxygen, produced by phorbol 12-myristate 13-acetate
activated neutrophils, into nonluminescent products is secreted by rat C6 glioma. The
enzyme was purified from chemically defined conditioned media and identified as an
extracellular superoxide dismutase (EC-SOD). The purified enzyme is distinct from human
EC-SOD C (Hjalmarsson, K., Marklund, SL, Engström, A., and Edlund, T.(1987) Proc. Natl.
Acad. Sci. USA 84, 6340-6344) by its elution from heparin-Sepharose at 300-400 mM NaCl …
