ABSTRACT
<p><b>OBJECTIVE</b>To explore the application of biosensor technology in the determination of endotoxin-neutralizing materials.</p><p><b>METHODS</b>After mixing polymyxin B (PMB) with endotoxin in certain concentration, the neutralizing ratio of PMB to endotoxin was assessed by biosensor technique and limulus amebocyte lysate test respectively. The results from the two methods were compared.</p><p><b>RESULTS</b>The neutralizing ratio of PMB to endotoxin as assessed by biosensor technology was 0.35 microg to 1 ng, while that by dynamic turbidimetric and chromogenic limulus amebocyte lysate (LAL) technique was 0.5 mg to 1 ng and 1 mg to 1 ng, respectively. The results obtained by biotechnology were similar to that by biosensor technique.</p><p><b>CONCLUSION</b>Biosensor technology was an accurate, convenient and rapid method for the determination of potency of endotoxin-neutralizing materials.</p>
