Lipopolysaccharides  (Synonyms: LPS)

Cat. No.: HY-D1056
COA Handling Instructions

Lipopolysaccharides (LPS) is an endotoxin derived from the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consists of an antigen O-specific chain, a core oligosaccharide and lipid A. Lipopolysaccharides is a pathogenic associated molecular pattern (PAMP) that activates the immune system. Lipopolysaccharides activates TLR-4 on immune cells. This product is derived from Escherichia coli O55:B5. Lipopolysaccharides induces secretion of cell migrasome.

    Description

    Lipopolysaccharides (LPS) is an endotoxin derived from the outer leaflet of the outer membrane of Gram-negative bacteria. Lipopolysaccharides consists of an antigen O-specific chain, a core oligosaccharide and lipid A. Lipopolysaccharides is a pathogenic associated molecular pattern (PAMP) that activates the immune system. Lipopolysaccharides activates TLR-4 on immune cells[1][2][3]. This product is derived from Escherichia coli O55:B5. Lipopolysaccharides induces secretion of cell migrasome[4].

    IC50 & Target

    TLR4

     

    In Vitro

    Lipopolysaccharides (10–80 μg/mL) selectively decreases THir (tyrosine hydroxylase immunoreactive) cells and increases culture media levels of interleukin1β (IL-1β) and tumor necrosis factor-α (TNF-α) as well as nitrite (an index of nitric oxide (NO) production)[5].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    In Vivo

    Lipopolysaccharides (1.5 mg/kg; i.p.; once) induces sickness and hypothermia in mice, and induces a greater and more prolonged sickness response in adult male mice[3].

    MCE has not independently confirmed the accuracy of these methods. They are for reference only.

    Animal Model: Female and male CD1 mice[3]
    Dosage: 1.5mg/kg
    Administration: Intraperitoneal injection, once
    Result: Induced sickness behavior in all mice, but adult mice displayed more sickness than pubertal mice and adult males remained sick for a longer period of time than adult females.
    Caused a decrease in body temperature for all mice, but this decrease was greatest in adult males.
    Increased pro- and anti-inflammatory cytokines at various levels in pubertal and adult male and female mice, resulted in age and sex differences in cytokine concentrations following immune challenge.
    Only adult males and females treated with LPS displayed significantly more IL-6 than their saline controls, and pubertal males and females and adult females displayed significantly more IL-10 than their saline controls.
    All the mice displayed significantly more IL-12 and TNF-α than their saline controls.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
