Cytotoxic pigment secreted by Pseudomonas aeruginosa, which frequently infects the lungs of immuno-suppressed patients, as well as those with cystic fibrosis. Pyocyanin toxicity results from its ability to undergo reduction by NAD(P)H and subsequent generation of superoxide and H2O2 directly in the lungs.
Product Details
Alternative Name: | Sanasin, 1-hydroxy-N-methylphenazine |
|
Formula: | C13H10N2O |
|
MW: | 210.2 |
|
CAS: | 85-66-5 |
|
Quantity: | 1 μmol |
|
Formulation: | Lyophilized. |
|
Purity: | ≥98% (HPLC) |
|
Quality Control: | Quality assayed by measuring the ability to increase the total ROS and superoxide levels in live cells using flow cytometry assays. Pyocyanin treatment of HeLa cells has to increase the percentage of green positive cells (total ROS levels) over 35% and orange positive cells (superoxide levels) over 70% compared to uninduced cells. |
|
Solubility: | Soluble in DMSO or dimethyl formamide. |
|
Reconstitution: | Reconstitute the contents of the vial in 100μl solvent to yield a 10mM stock solution. |
|
Shipping: | Dry Ice |
|
Short Term Storage: | -20°C |
|
Long Term Storage: | -80°C |
|
Use/Stability: | Stable for at least 1 year after receipt when stored at -80°C. |
