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.

Sample Tested: Urine and EDTA PlasmaVerified Customer | Posted 03/16/2023There appeared to be a urine matrix effect at 2-fold dilution. Tested plasma at 200-fold dilution and values were above the standard curve range.

Sample Tested: Serum and PlasmaVerified Customer | Posted 06/09/2020We used this kit to quantify the LBP in human serum and plasma samples. Works very well and generates a good standard curve.

Sample Tested: EDTA PlasmaVerified Customer | Posted 01/23/2020Performance and reproducibility of the kit are very good (see graph attached). Also, very good customer service and fast shipment. On the downside, the protocol is tricky to undstand.The information to perform the test is spread on three documents (the protocol, the certificate of analysis and the list of materials), so that pooling this information gives you quite the extra work.
