abstract：:A high molecular weight proteinaceous factor in the cell extract of sarcoma 180 (S-180) was found to inhibit phorbol myristate acetate (PMA)-triggering of macrophage H2O2 release. This factor (S-180 factor) was stable at 56 C for 1 hr and resistant to ultraviolet-irradiation. The S-180 factor inhibited the specific bi...
