Product Details
| Activity | Specific activator of Toll-like receptor 4 (TLR4). Does not activate TLR2 or other TLRs as determined with splenocytes and macrophages from TLR4 deficient mice. Smooth (S)-form LPS are commonly the preferred choice for whole animal studies, whereas Rough (R)-form LPS are primarily used in cellular in vitro activation studies. | 
|---|---|
| Alternative Name | Lipopolysaccharide from Salmonella enteritidis S-Form | 
| Couple Target | TLR, TLR4 | 
| Couple Type | Activator, Ligand | 
| Formulation | Liquid. Sterile, ready-to-use solution in pyrogen-free double distilled water. | 
| Purity | Absence of detectable protein or DNA contaminants with agonistic TLR activity. | 
| Source | Smooth (S)-form LPS isolated and purified from Salmonella enteritidis (wild type) by the hot phenol-water method and dissolved in sterile pyrogen-free double distilled water. |
