Fig. 3From: Dual functional β-peptide polymer-modified resin beads for bacterial killing and endotoxin adsorptionEffects of β-peptide polymer modified PA beads on the binding of LPS. a Illustration of the interaction between LPS and beads. b Beads were incubated with FITC-LPS (1 μg/mL) in PBS. c Beads cultivated with different concentrations of LPS in serum using the TAL assay, no significant differences among tests using 50–200 EU/mL of LPS. **p < 0.01Back to article page
