Cobra venom factor was used for the detection of factor B synthesized by mouse peritoneal macrophages. This method was shown to be specific for factor B assay by neutralization by antimouse factor B antibody. The amount of factor B in the culture supernatant, assessed by this method, was found to be dependent on the medium used for cultivation of macrophages. The addition of 25% L cell-conditioned medium to minimal essential medium (LCM-MEM) enhanced the production of factor B and also of lysozyme. Kinetic analysis in LCM-MEM showed that factor B produced by 6 x 10(4) cells/cm2 increased up to 72 hr and reached a plateau at 96 hr. The amounts of factor B and lysozyme produced in LCM-MEM depended upon the number of macrophages. Production of factor B was completely inhibited by 1 microgram of cycloheximide per ml and was restored by its removal.
