Detection of Human LBP by Western Blot

Detection of Human LBP by Western Blot

Western blot validation of proteins overexpressed in cancer sera. (A) Western blots of 50 μg of medium and low abundance proteins from each non-cancer (N1-N6) and cancer (C1-C6) serum pool depleted by the IgY12 HPLC column were probed with the antibodies to ECM1, LBP1, and alpha-1 antitrypsin. (B) A replicate of the PVDF blot was stained for total protein with colloidal gold as a control for loading/transfer. Bracket indicates the approximate region of the blot where proteins of interest would be expected. Image collected and cropped by CiteAb from the following open publication (https://proteomesci.biomedcentral.com/articles/10.1186/1477-5956-8-31), licensed under a CC-BY license.

Background: LBP

Lipopolysaccharide-binding protein (LBP), a 58 kDa glycoprotein synthesized in hepatocytes, belongs to a family of lipid-binding proteins which includes bactericidal/permeability increasing protein (BPI), phospholipid ester transfer protein (PLTP), and cholesterol ester transfer protein (CETP). LBP binds to the lipid A portion of lipopolysaccharide (LPS) to facilitate the process of LPS monomerization, catalyze the binding of LPS monomers to CD14, and promote LPS-induced immune response. LBP is present at low concentrations in normal human serum and may increase up to 30-fold during the acute phase response. Studies indicate that LBP also acts catalytically in the transfer of LPS to HDL, thus accelerating LPS detoxification. In addition, LBP and soluble CD14 can also function in phospholipid transport.
