Product Specification

SOURCE/HOST:	Isolated from E. coli R515 (Re mutant). Prepared by mild acid hydrolysis from purified Escherichia coli R515 (Re) LPS (isolated by a modification of the PCP extraction method [1,2]), converted to the uniform salt form [3] and dissolved in sterile pyrogen-free double distilled water.
CONCENTRATION:	1mg/ml
PURITY:	≥99.9% (regarding protein or DNA contaminants; KDO not detectable)
FORMULATION:	Liquid. Sterile, ready-to-use solution in pyrogen-free double distilled water.
ACTIVITY:	Activates Toll-like receptor (TLR) 4. Does not activate TLR2 or other TLRs as determined with splenocytes and macrophages from TLR4 deficient mice.
SHIPPING:	AMBIENT
LONG TERM STORAGE:	+4°C
HANDLING:	Keep sterile.
HAZARD:	HIGHLY PYROGENIC. HARMFUL.
