High Purity LPS & Lipid A Preparations do not Activate TLR2 or other TLRs

Activation of macrophages from TLR4 wild type compared to TLR4 deficient mice by TLRGRADE® LPS and TLRGRADE® Lipid A from Enzo Life Sciences. Lipid A or LPS concentrations, which induced maximal activation of TLR4 wild type mouse macrophages, were also applied to TLR4 deficient mouse macrophages (105) as follows: 80ng Salmonella LPS (S. minnesota R595 Re), 80ng E. coli LPS (R515 Re), 400ng E. coli Lipid A (R515 Re) and 400ng Salmonella LPS (S. abortus equi S-form). 10 units of IL-6 correspond to the detection limit of the IL-6 ELISA.
