Biotin-Lipopolysaccharide, fromE.coliO111:B4, is a biotin-conjugated Lipopolysaccharide (LPS) capable of binding with streptavidin proteins. Biotin-Lipopolysaccharide, fromE.coliO111:B4, can be utilized for the identification of Lipopolysaccharide ligands.

Lipopolysaccharides from *E. coli* (Escherichia coli) O26:B6 are endotoxins derived from *E. coli* that function as TLR-4 activators. These S-type LPS molecules can trigger pathogenic-associated molecular patterns (PAMP) and encourage the release of exosomes. Structurally, they are composed of three parts: O-antigen, core oligosaccharide, and Lipid A, and can be identified by the monoclonal antibody MAb J8-4C10. This compound can increase pro-inflammatory cytokines in plasma, leading to activation of the hypothalamic-pituitary-adrenal (HPA) axis and causing oxidative damage to the adrenal glands. However, the pathogenic activity of Lipopolysaccharides from *E. coli* O26:B6 can be inhibited by PD149163 .

Lipopolysaccharides from E. coli O127:B8 (LPS, from Escherichia coli (O127:B8)) are endotoxins and TLR-4 activators extracted from the bacterium E. coli O127:B8. This smooth (S) type LPS features a typical tripartite structure: an O antigen, an R3 core oligosaccharide, and lipid A. When lipopolysaccharides from E. coli O127:B8 activate TLR-4 on immune cells, they can trigger inflammatory responses and ileal contractility, making them useful for developing intestinal inflammation models.

Lipopolysaccharides, from E. coli O128:B12 (LPS, from Escherichia coli [O128:B12]) are lipid polysaccharide endotoxins and TLR-4 activators derived from E. coli O128:B12, characterized as a smooth (S) type LPS. This compound features a typical three-part structure: O antigen, R3 core oligosaccharide, and lipid A. It activates TLR-4 in immune cells, is useful for developing neonatal brain inflammation models in animals, and may impact preterm birth in neonates.

Lipopolysaccharides, from E. coli (Escherichia coli) K-235, are endotoxins derived from Escherichia coli and serve as TLR-4 activators. They are an S-type LPS capable of activating pathogen-associated molecular patterns (PAMP) of the immune system and inducing the secretion of exosomes. This compound is characterized by a typical three-part structure comprising the O-antigen, core oligosaccharide, and Lipid A. Additionally, lipopolysaccharides from E. coli K-235 stimulate mitogenesis in C57BL/10ScN spleen cells and, when purified by butanol and deoxycholate methods, can stimulate spleen cells from C57BL/10ScCR and C3H/HeJ mice.

Glycol chitosan, a chitosan derivative with hydrophilic ethylene glycol branches, inhibits E. coli, S. aureus, and S. enteritidis growth (MICs: 4 μg/mL, 32 μg/mL, and <0.5 μg/mL), and enhances membrane permeability and leakage in Glycine max [Harosoy 63W] cells.

5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine (5'-O-DMT-dU) is a competitive inhibitor of dUTP nucleotidohydrolase (dUTPase) in E. coli with a Ki greater than 1 mM. 5'-O-(4,4'-Dimethoxytrityl)-2'-deoxyuridine can be used in machine-assisted DNA synthesis.

E. coli Extract Total is derived from Escherichia coli (ATCC 11303) cultured under 37°C conditions during its three-quarters logarithmic growth phase, and it is suitable for use in the preparation of unilamellar vesicles.

E. coli Extract Polar is a polar lipid extract from Escherichia coli, consisting of phosphatidylethanolamine, phosphatidylglycerol, and cardiolipin, useful for reconstituting membrane proteins.

E. coli DNAligase is an NAD++ dependent enzyme that catalyzes the formation of phosphodiester bonds between the complementary 3′-OH and 5′-P ends of double-stranded DNA (dsDNA).

E.coli tRNA adenosine deaminase is derived from Escherichia coli and functions as an adenosine deaminase. It effectively deaminates adenine within single-stranded RNA (ssRNA, primarily in the loop regions of tRNA) or double-stranded RNA (dsRNA) but lacks deaminase activity on DNA. This enzyme is a protein-engineered mutant form of adenosine deaminase, efficiently deaminating adenine in ssDNA, making it useful for adenine base editing (ABE) and RNA m6A methylation sequencing.

Methyl picolinate (Methyl picolinate) is used as pharmaceutical intermediate.

Pipecolic acid (2-Piperidinecarboxylic acid), a metabolite of lysine found in human physiological fluids such as urine, plasma and CSF, is an important regulator of immunity in plants and humans alike.
