FIG. 2.

The kinetics of LPS neutralization by Lp(a) and LDL. The kinetics of neutralization was investigated by preincubation of LPS with lipoproteins for various time intervals. The lipoproteins needed more than 8 h to neutralize half of the TNF production induced by LPS, while the neutralization was more than 70% when LPS was preincubated with Lp(a) or LDL for 24 h. No differences in the kinetics of LPS neutralization by Lp(a) and LDL could be observed. The data represent means plus or minus the standard deviations of three experiments with similar results (n = 6).
