Product Details

Source: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), converted to the uniform salt form and dissolved in sterile pyrogen-free double distilled water.
Formulation:Liquid. Sterile, ready-to-use solution in pyrogen-free double distilled water.
Purity:≥99.9% (regarding protein or DNA contaminants; KDO not detectable)
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 Temperature
Long Term Storage:+4°C
Handling:Keep sterile.
Regulatory Status:RUO - Research Use Only

Figure: Activation of macrophages from TLR4 wild type compared to TLR4 deficient mice by LPS and Lipid A from Enzo. Lipid A or LPS concentrations, which induced maximal activation of TLR4 wild type mouse macrophages, were also applied to TLR4 deficient mouse macrophages. 10 units of IL-6 correspond to the detection limit of the IL-6 ELISA.
