5%DMSO 40%PEG300 5%Tween80 50%ddH2O
5.0mg/ml Taking the 1 mL working solution as an example, add 50 μL of 100 mg/ml clarified DMSO stock solution to 400 μL of PEG300, mix evenly to clarify it; add 50 μL of Tween80 to the above system, mix evenly to clarify; then continue to add 500 μL of ddH2O to adjust the volume to 1 mL. The mixed solution should be used immediately for optimal results. 
Clear solution
5% DMSO 95% Corn oil
0.625mg/ml Taking the 1 mL working solution as an example, add 50 μL of 12.5 mg/ml clear DMSO stock solution to 950 μL of corn oil and mix evenly. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
* Room temperature shipping (Stability testing shows this product can be shipped without any cooling measures.)

Biological Activity

Description Rifampin (Rifampicin) is a DNA-dependent RNA polymerase inhibitor, used to treat a number of bacterial infections.
Targets
RNA polymerase [1]
In vitro

Rifampin inhibits IκBα degradation and mitogen-activated protein kinase (MAPK) phosphorylation. Rifampin is found to bind to human MD-2 in a Rifampin and MD-2 concentration-dependent manner. Rifampin inhibits NF-κB activation induced by LPS (20 ng/ml) in a dose-dependent manner, with an IC50 of 44.1 μM in Blue hTLR4 293 cells (A) and immunocompetent microgial BV-2 cell. Rifampin (50 μM) suppresses NF-κB activation at varying LPS doses, and the maximum NF-κB level induced by LPS in the presence of Rifampin (50 μM) is much lower than that in the absence of Rifampin. Rifampin inhibits NO production induced by LPS (200 ng/ml) in a dose-dependent manner in BV-2 cells, with an IC50 of 21.2 μM. Rifampin suppresses LPS induced TNF-α and IL-1β production in both microglia BV-2 and RAW 264.7 macrophage cells. Rifampin-inhibiting innate immune signaling is independent of the pregnane X receptor NR1I2. [1] Rifampin combined with polyester vascular prostheses (PVP) functionalised with cyclodextrin (PVP-CD) results in significant bacterial adhesion reduction and growth inhibition against Gram-positive bacteria. [2] Rifampin (50 μg/mL) significantly reduces the CFU counts of stationary-phase cultures and reduces the CFU counts of the log-phase culture to zero. Rifampin is particularly suitable since it is bactericidal and starts killing M. tuberculosis within an hour of exposure. [3]
