mesangial cells incubated with c5b6 + serum , which results in cell membrane interaction with the mac , produce 0.9 +/- 0.15 nmol o2-/10 ( 5 ) cells per 30 min , which was significantly greater than the amount produced by cells incubated with c5b6 alone , serum alone , or decayed macs that can no longer interact with the cell membrane ( 0.3 +/- 0.2 , 0.4 +/- 0.1 , 0.3 +/- 0.2 nmol o2-/10 ( 5 ) cells per 30 min , respectively ; p less than 0.02 ) .
