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[1].

Target	TLR4
In Vitro	Kdo2-Lipid A (1 µM) stimulates the release of both TNF and PGE2 from the adult rat spinal astrocytes cell cultures[1]. RT-PCR[1] Cell Line: TNF and PGE2 Concentration: 1 µM Incubation Time: Result: Amounts of protein (mg) is 6.2 ± 0.6 ng/mL and 1.4 ± 0.3 ng/mL for TNF and PGE2.
In Vivo	KDO2-Lipid A (i.t.) activates toll-like receptor 4 (TLR4) in rats[1]. Animal Model: Rats (Male Holzman Sprague-Dawley, 300–400 g) [1] Dosage: 0.1 to 10 µg Administration: I.T.; 0.1-10 µg; prior and 15, 30, 60, 90 and 120 min after injection of Kdo2-Lipid A. Result: Intrathecal injection of 1 µg Kdo2-Lipid A induces allodynia, and the animals appeared to be sick after i.t. injection of Kdo2-Lipid A.
