설명

일반 설명

Lipopolysaccharide (LPS), also known as endotoxin, is present mainly in the cell wall of Gram-negative bacteria. It comprises three structural regions the O-side chain, a middle polysaccharide component, and Lipid A which contributes to the pyrogenic nature of LPS.

애플리케이션

LPS, E. Coli O111:B4 has been used for priming macrophages to upregulate genes necessary for NOD-, LRR- and pyrin domain-containing protein 3 (NLRP3) inflammasome activation. It has also been used to stimulate Raw264.7 cells before pull-down assay.

생화학적/생리학적 작용

Lipopolysaccharide (LPS), an effective immunostimulant induces inflammatory and immune responses by activating Toll-Like Receptor 4 (TLR4). It also contributes to osteoclastogenesis in mice. LPS serves as a permeability barrier around the cell surface to restrict the entry of toxic molecules such as antibiotics and bile salts. It acts as a pyrogenic agent and eventually induces septic shock in host cells.

품질

ANAYLISIS: <3% protein by Lowry assay.

물리적 형태

Liquid in PBS, pH 7.4.

Endotoxin Activity: Not less than 500,000 Endotoxin Units per mg of LPS as measured by the gel clot assay; chromogenic (Cambrex assays) toxicity assay measurements demonstrate approximately 10 EU/nanogram of LPS.

저장 및 안정성

Maintain at 2-8°C for up to 6 months in undiluted aliquots.

Good laboratory technique should be employed in the safe handeling of any lipopolysaccharide or lipid A product.

This requires observing the following practices:

1. Wear appropriate laboratory attire including a lab coat, gloves and safety glasses.

2. Do not mouth pipette, ingest or allow to come into contact with open wounds. Wash thoroughly any area of the body which comes into contact with the product.

3. This product is pyrogenic. Avoid accidental autoinjection by exercising extreme care when handling in conjunction with any injection device.
