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.
Rough (R)-form LPS isolated and purified from E. coli EH100 (Ra-mutant) by a modification of the PCP extraction method, converted to the uniform sodium salt form and dissolved in sterile pyrogen-free double distilled water., Absence of detectable protein or DNA contaminants with agonistic TLR activity. | Print as PDF

Smooth (S)-form LPS isolated and purified from E. coli 055:B5 by a modification of the phenol water extraction and PCP extraction method, converted to the uniform sodium salt form and dissolved in sterile pyrogen-free double distilled water., Absence of detectable protein or DNA contaminants with agonistic TLR activity. | Print as PDF
Smooth (S)-form LPS, isolated and purified from Salmonella abortus equi by modification of the phenol water extraction and PCP method, converted to the uniform salt form and dissolved in pyrogen-free double distilled water., Absence of detectable protein or DNA contaminants with agonistic TLR activity. | Print as PDF
Smooth (S)-form LPS, isolated and purified from Salmonella abortus equi by modification of the phenol water extraction and PCP method. LPS-Biotin was prepared using the biotin reagent biotinamidocaproate N-hydroxysuccinimide ester. Briefly, LPS at 10mg/ml in distilled water was mixed with biotin reagent in sodium bicarbonate buffer. The reaction mixture was stirred, dialyzed extensively against distilled water in the dark, and sterile filtered., Absence of dectectable protein or DNA contaminants with agonistic TLR activity. | Print as PDF
