Table 3 Endotoxin levels in EHC-93 total and its water-insoluble and soluble fractions

From: In vitro toxicoproteomic analysis of A549 human lung epithelial cells exposed to urban air particulate matter and its water-soluble and insoluble fractions

PM Endotoxin (EU/kg materiala)
Totalb 100.0 ± 1.0
Insoluble 91.6 ± 1.4
Soluble 2.5 ± 1.0
  1. aThe quantity of endotoxin unit (EU) was expressed relative to EHC-93 total for direct comparison (i.e., 91.6 and 2.5 EU can be detected from 0.83 and 0.17 kg of materials from the insoluble and soluble fractions, respectively)
  2. bData has been published [8]
