Product Details
| Alternative Name: | Lipopolysaccharide from Salmonella abortus equi S-form |
| |
| Source: | 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. |
| |
| Concentration: | 1mg/ml |
| |
| 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. |
| |
| Activity: | Strong activator of Toll-like receptor (TLR) 4. Does not activate TLR2 or other TLRs as determined with splenocytes and macrophages from TLR4 deficient mice. No further re-extraction required.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. |
| |
| Shipping: | Ambient Temperature |
| |
| Long Term Storage: | +4°C |
| |
| Use/Stability: | Stable for at least 1 year after receipt when stored at +4°C. |
| |
| Handling: | Do not ingest. Wear gloves and mask when handling this product! Avoid contact through all modes of exposure. LPS compounds are highly pyrogenic. Avoid accidental injection; extreme care should be taken when handling in conjunction with hypodermic syringes Use must be restricted to qualified personnel. Keep sterile. |
| |
| Technical Info/Product Notes: | For the biotinylated LPS, please see Prod. No. ALX-581-150. |
| |
| 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.
