"Endotoxin (LPS) preparations are widely used to study the structure, metabolism, immunology, and biosynthesis of LPS. LPS is also used to induce the synthesis and secretion of growth-promoting factors such as interleukins. By combining LPS with FITC, TRITC, and TNP, it can be used to study intracellular responses such as immune response to LPS.
