Therefore, enhanced strategies will be Particularly useful in demasking and capturing LPS molecules in circulating blood. Thus, new strategies may very well be valuable in detecting the presence of trace quantities of endotoxin inside the blood and correctly analyzing the clinical outcome of direct hemoperfusion and the therapeutic potential of latest drug candidates, including anti-endotoxin brokers and antimicrobial peptides [84].
