  • HY-D1056
    Lipopolysaccharides, from E. coli O55:B5
    		Activator
    Lipopolysaccharides, from E. coli O55:B5 (LPS, from Escherichia coli (O55:B5)) are endotoxins and TLR4 activators extracted from Escherichia coli (E. coli O55:B5) and are classified as S (smooth) type LPS. Lipopolysaccharides, from E. coli O55:B5 possess the typical three-part structure: O-antigen, core oligosaccharide, and lipid A. Lipopolysaccharides, from E. coli O55:B5 activate TLR-4 in immune cells, exhibit high pyrogenicity, and demonstrate dose and serotype specificity. Lipopolysaccharides, from E. coli O55:B5 can be used to induce cellular inflammation and establish animal models related to inflammation.
    It is recommended to prepare a stock solution of ≥10 mg/mL. Due to the adsorption characteristics of LPS, low adsorption centrifuge tubes should be used for aliquoting and storage.
  • HY-N8277
    Kdo2-Lipid A ammonium
    		Activator 99.00%
    Kdo2-Lipid A ammonium is a chemically defined lipopolysaccharide (LPS) with endotoxin activity equal to LPS. Kdo2-Lipid A ammonium is highly selective for TLR4. Kdo2-Lipid A ammonium stimulates the release of both TNF and PGE2.
  • HY-165632
    Creatine ethyl ester
    		Activator
    Creatine ethyl ester (CEE) is a readily available form of creatine used in supplements. Creatine ethyl ester (CEE) upregulates TLRs (TLR2, 3, 4 and TLR7) over the short-term.
