Influence of different anticoagulants on endotoxin activity in plasma. Increasing concentrations of unfractionated heparin, lovenox, fondaparinux and citrate was added to human serum. Subsequently, 5 ng/mL LPS (E. coli) was spiked and the endotoxin activity was measured by LAL test. The endotoxin activity is expressed as a percentage and refers to the serum sample without anticoagulant set at 100%. Mean ± standard deviation of three independent experiments with plasma/serum from different donors are shown.
