Kdo2-Lipid A (KLA) A87500 (Previously 699500) Di[3-deoxy-D-manno-octulosonyl]-lipid A (ammonium salt)
A new preparation of the saccharolipid glycan, Kdo2-Lipid A (KLA), is a nearly homogeneous Re lipopolysaccharide (LPS) substructure with endotoxin activity equal to that of native LPS. KLA is comparable to LPS and its activity is reduced by >103 in cells from TLR-4 deficient mice. The advantage of KLA over LPS is that it is a reproducible, defined natural product, and it can be detected by ESI/MS at the low concentrations used to stimulate animal cells. The purity of KLA should also facilitate the structural analysis of its complexes with signaling receptors, such as TLR-4/MD2.
New research* shows 1μg KLA induces
the same response as 10μg LPS.
