蛋白结构(Molecular Characterization)
This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 52.8 kDa. The protein migrates as 62 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
内毒素(Endotoxin)
Less than 1.0 EU per μg by the LAL method.
纯度(Purity)
>95% as determined by SDS-PAGE.
制剂(Formulation)
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

电泳(SDS-PAGE)
Human Lipopolysaccharide, His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
背景(Background)
Lipopolysaccharide-binding protein (LBP),a member of the BPI/LBP/Plunc superfamily, BPI/LBP family, is detected in blood serum. LBP plays a role in the innate immune response. Alao,LBP can bind to the lipid A moiety of bacterial lipopolysaccharides (LPS), a glycolipid present in the outer membrane of all Gram-negative bacteria, and act as an affinity enhancer for CD14, facilitating its association with LPS. Furthermore, LBP is able to promote the release of cytokines in response to bacterial lipopolysaccharide.
