Product Overview
This rabbit polyclonal antibody targets lipopolysaccharide-binding protein (gene LBP) in human, mouse and rat samples and is validated for Western blot. The predicted molecular weight is 53.4 kDa, and the supplier reports an observed band at about 65 kDa.
Lipopolysaccharide-binding protein (LBP) is an acute-phase plasma protein made mainly by the liver. It binds the lipid A part of bacterial lipopolysaccharide and hands it to CD14, which then presents it to the TLR4/MD-2 receptor, greatly increasing cell sensitivity to Gram-negative bacteria. LBP is studied in innate immunity, sepsis and inflammation research.

Validated Applications
| Western blot | 0.1–0.5 µg/mL (Human, Mouse, Rat) |
|---|
Samples with a confirmed band (WB): rat thymus tissue, mouse thymus tissue, HeLa cells, K562 cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Conditions in the example images (WB): 5–20% gradient SDS-PAGE under reducing conditions, 50 µg lysate per lane, transfer to nitrocellulose membrane, blocking in 5% non-fat milk, primary antibody at 0.5 µg/mL overnight at 4 °C, HRP-conjugated secondary antibody at 1:10000, ECL detection.
Immunogen
Recombinant human LBP fragment (Leu177–Glu446), expressed in E. coli. Sequence identity with the mouse and rat orthologs: 68.5% and 69.6%, respectively.
Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt describes lipopolysaccharide-binding protein as secreted and also located in the cytoplasmic granule membrane. Tissue expression noted by UniProt (human): Detected in blood serum (at protein level). The samples tested by the supplier (listed above) are a practical starting point for positive controls.
