From: Bovine lactoferrin free of lipopolysaccharide can induce a proinflammatory response of macrophages
Presence of phosphorylated form of NIK in porcine monocyte-derived macrophages after stimulation with (from right to left) 1 μg/ml of lipopolysaccharide (LPS); 100 μg/ml of purified (LF) of unpurified lactoferrin (LF-LPS) containing 0.05 EU/ml or 4.10 EU/ml, respectively. Cells cultivated in LPS-free medium were used as a control. β-actin served as loading control
