LBP: Lysates

Lipopolysaccharide-binding protein (LBP), a 58kDa glycoprotein synthesized in hepatocytes, belongs to a family of lipid-binding proteins that includes bactericidal/permeability increasing protein (BPI), phospholipid ester transfer protein (PLTP), and cholesterol ester transfer protein (CETP). LBP binds to the lipidA portion of lipopolysaccharide (LPS) to facilitate the process of LPS monomerization, catalyzes the binding of LPS monomers to CD14, and promotes LPS-induced immune response.
