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.

In Vitro
Cetrimonium bromide (1-5 μM, 24 h) cannot affect growth of SK-HEP-1 cells[1].
Cetrimonium bromide (5 μM, 16-24 h) attenuates cellular migration and invasion of SK-HEP-1cells[1].
Cetrimonium bromide (5 μM, 24 h) inhibits the protein expression of MMP-2 and MMP-9, increases the protein expression of TIMP-1 and TIMP-2 and restrain the protein expression of Rac1, cdc42 and RhoA in SK-HEP-1cells[1].
Cetrimonium bromide (5 μM, 12-72 h) induces apoptosis in human Head and neck cancer (HNC) cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

용액&용해도
In Vitro:
DMSO : 10 mg/mL (27.44 mM; Need ultrasonic; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
H2O : 4.55 mg/mL (12.48 mM; Need ultrasonic)
Please refer to the solubility information to select the appropriate solvent. Once prepared, please aliquot and store the solution to prevent product inactivation from repeated freeze-thaw cycles.
Storage method and period of stock solution: -80°C, 6 months; -20°C, 1 month (sealed storage, away from moisture and light). When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.
* Note: If you choose water as the stock solution, please dilute it to the working solution, then filter and sterilize it with a 0.22 μm filter before use.

In Vivo:
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
Solubility: ≥ 1 mg/mL (2.74 mM); Clear solution
This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 1 mg/mL (2.74 mM); Clear solution
This protocol yields a clear solution of ≥ 1 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (10.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.

For the following dissolution methods, please prepare the working solution directly:
It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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.
