Biological Activity
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.
DMBA can induce breast cancer and skin cancer models. Oral administration of DMBA (0-150 mg/kg) leads to a reduction in spleen weight and a decrease in the total number of lymphocytes recovered from the spleen in C57BL/6 mice. In SD rats, DMBA exhibits a terminal deposition half-life of 45 minutes across all dose ranges (5-50 mg)[5].
Administration: 15-20 mg DMBA-• intragastric gavage • single dose
Histology analysis:The tumor exhibits tightly spaced chords epithelial cells, cysts and papillary structures.
Phenotype:develops a temporary cessation in body growth.
Administration: 25 mg DMBA • applied on the shaved back skin • single dose
Administration: 5-20 mg/kg • intratracheal instillation • single dose.
(2). A coat of antibiotic is applied after the instillation.
Histology analysis:Inflammation with alveolar epithelial hyperplasia, adenic metaplasia, adenomatoid hyperplasia and atypical hyperplasia.

Solvent & Solubility
Acetone : 25 mg/mL (97.52 mM; Need ultrasonic)
DMSO : ≥ 12.5 mg/mL (48.76 mM; Hygroscopic DMSO has a significant impact on the solubility of product, please use newly opened DMSO)
Ethanol : 3.33 mg/mL (12.99 mM; ultrasonic and warming and heat to 60°C)
* "≥" means soluble, but saturation unknown.
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. When stored at -80°C, please use it within 6 months. When stored at -20°C, please use it within 1 month.

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 90% (20% SBE-β-CD in Saline)
Solubility: 2.5 mg/mL (9.75 mM); Suspended solution; Need ultrasonic
This protocol yields a suspended solution of 2.5 mg/mL. Suspended solution can be used for oral and intraperitoneal injection.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
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.
