Cetrimonium bromide
Based on 2 publication(s) in Google Scholar
Cetrimonium bromide (CTAB), a quaternary ammonium, is an orally active cationic surfaetant. Cetrimonium bromide has toxicity and anticancer effect. Cetrimonium bromide inhibits cell migration and invasion through modulating the canonical and non-canonical TGF-β signaling pathways. Cetrimonium bromide can be used for DNA extraction.

Select the appropriate dissolution method based on your experimental animal and administration route.
- For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
- To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
- The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.
Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
