Application
FITC-Lipopolysaccharides (FITC-LPS) may be used to study the movement/transport of LPS across tissue barriers such as the colonic epithelium and cellular binding and internalization of lipopolysaccharides with fluorescence-based assay systems. FITC-LPS may be used to evaluate, qualify and quantify lipopolysaccharides (LPS) removal reagents and procedures. FITC-LPS conjugate may be used for the detection of LPA binding proteins and motifs.
Lipopolysaccharides (LPSs) are characteristic components of the cell wall of Gram-negative bacteria. LPS and its lipid A moiety stimulate cells of the innate immune system by the Toll-like receptor 4 (TLR4), a member of the Toll-like receptor protein family, which recognizes common pathogen-associated molecular-patterns (PAMPs).
Biochem/physiol Actions
Lipopolysaccharides (LPS) are localized in the outer layer of the membrane and are, in noncapsulated strains, exposed on the cell surface. They contribute to the integrity of the outer membrane, and protect the cell against the action of bile salts and lipophilic antibiotics.
General description
This product is a TCA extract of E. coli serotype O55:B5 (strain CDC 1644-70), which was purified by gel filtration and conjugated to FITC (fluorescein isothiocyanate).

Preparation Note
The product is soluble in water (5 mg/ml), yielding a hazy faint yellow solution. Lipopolysaccharides are molecules that form micelles in every solvent. Hazy solutions are observed in water and phosphate buffered saline. Organic solvents do not give clearer solutions. Methanol yields a turbid suspension with floaters, while water yields a homogeneously hazy solution.

Infectious diseases in early postnatal ontogenesis often result in cognitive impairments, particularly learning and memory. The essential foundation of learning and memory is long-term synaptic plasticity, which depends on N-methyl-D-aspartate (NMDA) receptors. In the present study, bacterial infection was modeled
