MBA is a bioactive molecule.

Dicamba-6-amino-6-oxohexanoic acid (DCh) is a hapten molecule that becomes activated upon the removal of the 1-tert-butyl-benzoate moiety.

Lipopolysaccharides, from Proteus vulgaris, are endotoxins sourced from the bacterium Proteus vulgaris, functioning as TLR-4 activators and representing S-type LPS. They play a role in activating pathogen-associated molecular patterns (PAMP) and stimulate cells to secrete migration-inducing agents. This lipopolysaccharide displays a characteristic three-part structure: O antigen, core oligosaccharide, and lipid A. Furthermore, it has a unique molecular configuration and a chitosan affinity (Kb=2.72 μM), which is superior to that of Yersinia pseudotuberculosis (Kb=6.06 μM) and Escherichia coli (Kb=79.50 μM).

Lipopolysaccharides, fromProteus mirabilis, are endotoxins derived from the bacterium Proteus mirabilis, functioning as TLR-4 activators and featuring an S-type LPS structure. They play a role in activating pathogen-associated molecular patterns (PAMP) and inducing cell-extracellular vesicle release. These lipopolysaccharides have a classic tripartite structure: O antigen, core oligosaccharide, and lipid A. Proteus mirabilis is a primary pathogen responsible for urinary tract infections and has potential links to rheumatoid arthritis. Additionally, Lipopolysaccharides, fromProteus mirabilis, exhibit promising antitumor effects, showing in vivo inhibitory activity against solid tumors such as meningeal sarcoma and Walker carcinoma.

Lipopolysaccharides, from Salmonella typhosa, are endotoxins and TLR-4 activators originating from Salmonella typhosa. These S-type lipopolysaccharides can stimulate the immune system's pathogen-associated molecular patterns (PAMP) and induce cellular secretion of migratory bodies. They exhibit a typical three-part structure: O antigen, core oligosaccharide, and lipid A. These lipopolysaccharides can function as vaccine adjuvants, enhancing the immune response, particularly by modulating B cell activity.

DEAE-dextran, MW 500000 hydrochloride (DEAE-dextran, MW 500000 hydrochloride, from bacterial [Leuconostoc mesenteroides]) is a high molecular weight, positively charged polymer that notably enhances the uptake of viral RNA by cultured cells. It is employed in "tumor immunity" RNA-spleen cell transfer systems, significantly prolonging the lifespan of tumor-bearing animals, comparable to those with active immunity. DEAE-dextran acts as a nucleic acid complexing agent, forming composite particles with DNA/RNA, and is widely used in gene delivery. Additionally, it serves as a coating for liposomes.

Eosin-Methylene Blue Agar (EMB Agar) is a biochemical reagent used for microbial cultivation.

Levine Eosin-Methylene Blue Agar Medium (Levine EMB Agar) is a mildly selective culture medium used for isolating enteric pathogens, especially Escherichia coli. The composition per liter of Levine Eosin-Methylene Blue Agar Medium includes: 10.0 g peptone, 10.0 g lactose, 2.0 g dipotassium phosphate, 15.0 g agar, 0.4 g eosin, and 0.065 g methylene blue.
