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.

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.

Phosphatase, Escherichia coli (EC 3.1.3.-), is an enzyme that removes phosphate groups from substrates, generating phosphate ions and molecules with free hydroxyl groups through the hydrolysis of phosphate monoesters.

Trehalose-6-phosphate hydrolase, Escherichia coli (EC 3.2.1.93), is a member of the hydrolase family, functioning as a glycosidase that hydrolyzes O- and S-glycosyl compounds. This enzyme plays a role in the metabolism of starch and sucrose, with substrates α,α-trehalose-6-phosphate and water, producing D-glucose and D-glucose-6-phosphate.

Sugar-phosphatase, Escherichia coli (EC 3.1.3.23) is a member of the hydrolase enzyme family, specifically targeting the hydrolysis of phosphomonoester bonds. Its substrates include sugar phosphates and water, with its reaction products being sugar and phosphate.

α-Galactosidase, positionally specific, Escherichia coli (EC 3.2.1.22), is a glycoside hydrolase enzyme that catalyzes the hydrolysis of α-galactosyl residues from the termini of glycolipids and glycoproteins. It exists in two recombinant forms known as α-galactosidase (INN) and β-galactosidase (INN).

α-Glucosidase, Escherichia coli (EC 3.2.1.20), is a glucosidase found in the brush border of the small intestine that acts on 1,4-α-glycosidic bonds, breaking down starches and disaccharides into glucose.

α-Amylase, Escherichia coli (EC 3.2.1.1) is a protein enzyme that hydrolyzes the α-glycosidic bonds of large α-linked polysaccharides, such as starch and glycogen, producing glucose and maltose.

Lipopolysaccharides from Escherichia coli O111:B4 are key components of the outer membrane of Gram-negative bacteria. As a smooth-type LPS, they consist of lipid A, an R3-type core oligosaccharide, and an O-specific polysaccharide. These LPS molecules exhibit high immunogenicity, can trigger strong immune responses and gastric disorders by activating the TLR-4 receptor on immune cells, and help maintain the structural integrity of the bacterial outer membrane while protecting against bile salts and lipid-based antibiotics. They are widely used to establish inflammation-related disease models, such as chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ARDS).
