商品コード	AG-CU1-0001
品名	Kdo2-Lipid A (ready-to-use)
分子式	C110H198N2Na4O39P2
分子量	2326.7
CAS	123621-04-5 (free base)
構造式	-
純度	Absence of detectable protein or DNA contaminants with agonistic TLR activity.
形状	Clear, colorless solution.
別名	(3-Deoxy-D-manno-octulosonic acid)2-Lipid A
特長	Defined substructure of the Re mutant of lipopolysaccharide (LPS) [1]. Endotoxin activity equal to Re LPS [1]. Strong activator (<10ng/ml) of macrophages via toll-like receptor 4 (TLR4) [1, 2, 3, 4, 9]. Does not activate TLR2 [5] or other TLRs as determined with splenocytes and macrophages from TLR4 deficient mice by IL-6 ELISA [1,4]. Facilitates the structural analysis of its complexes with signaling receptors, such as TLR4/MD2 [1,2] and CD14 [7]. Kdo2-Lipid A was used in a recent animal atherosclerosis model [6]. Induces sphingolipid biosynthesis, which is essential for induction of autophagy [8].
