Source

Human Lipopolysaccharide-binding Protein ,His Tag, Ala 26 - Val 481 (Accession # P18428), was produced in human 293 cells (HEK293) at ACROBiosystems.

Molecular Characterization

Human LBP / Lipopolysaccharide Protein ,His Tag is fused with a polyhistidine tag at the C-terminus, and has a calculated MW of 52.8 kDa. The predicted N-terminus is Ala 26. DTT-reduced Protein migrates as 62 kDa in SDS-PAGE due to glycosylation.

Endotoxin

Less than 1.0 EU per μg of the Human LBP / Lipopolysaccharide Protein ,His Tag by the LAL method.

Purity

>95% as determined by SDS-PAGE.

Formulation

Lyophilized from 0.22 μm filtered solution in PBS, pH 7.4. Normally Mannitol or Trehalose are added as protectants before lyophilization.

Contact us for customized product form or formulation.

Reconstitution

See Certificate of Analysis for reconstitution instructions and specific concentrations.

Storage

Avoid repeated freeze-thaw cycles.

No activity loss was observed after storage at:
In lyophilized state for 1 year (4oC); After reconstitution under sterile conditions for 3 months (-70oC).

 

SDS-PAGE


Human LBP / Lipopolysaccharide Protein
The purity of Human LBP / Lipopolysaccharide Protein ,His Tag was determined by DTT-reduced (+) SDS-PAGE and staining overnight with Coomassie Blue.
 
 

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.
