Recombinant Human Lipopolysaccharide Binding Protein, His-tagged

• Cat.No.: LBP-4927H
• Product Overview: Recombinant human LBP containing His tag was expressed by baculovirus in CHO cells and having a molecular mass of 58.0 kDa.

Specification

• Cat. No.: LBP-4927H
• Description: Natural LBP is a 58 kDa glycoprotein produced in liver. It binds at lipid A of LPS with high affinity (10-9M) and reduced the cellular LPS effects at CD14+ cells (IL1ß, IL6, TNFα). It acts as opsonin for GRAM negative cells, LPS, neutrophils and granulocytes. This is a His-tagged protein
• Biological Activity: Up to 0.2 µg/ ml LBP mediates binding of FITC-LPS (0.5µg/ml) to CD14+CHO transfectants (FACS).
• Molecular Weight: 58.0 kDa
• Source: CHO cells
• Species: Human
• Form: Lyophilized from a concentrated protein solution (0.25mg/ml) containing PBS, pH 7.2
• Endotoxin Level: < 0.03 ng/ ml
• Appearance: Lyophilized protein
• Reconstitution: Centrifuge the vial prior to opening. Reconstitute in 40 µl of ultra-pure distilled water. This solution can then be diluted into other aqueous buffers and stored at -20°C or -70°C for future use.
• Purity: >90-95% by SDS-PAGE analyses
• Storage: The lyophilized protein is best-stored desiccated below 0°C. Reconstituted protein should be used immediately or stored in undiluted working aliquots at -20°C. For long term storage it is recommended to add a carrier protein (0.1% BSA). Repeated freezing and thawing should be avoided.
• Pathways: Toll-like receptor signaling pathway; Signaling in Immune system
