Biological Activity

Description

7,12-Dimethylbenz[a]anthracene (DMBA) is an immunosuppressor as well as a potent organ-specific carcinogen.
In vitro
In vitro

In splenocytes, which is isolated from mice, lymphocyte function is completely suppressed by the treatment with 50 μM DMBA. The susceptibility of splenocytes isolated from mEH-null mice is lower than from wildtype mice on the immunosuppression activity of DMBA.[1]
Cell Research Cell lines Splenocytes
Concentrations 10 μM, 20 μM, 50 μM
Incubation Time --
Method

Spleens are harvested and placed in a sterile phosphatebuffered saline. Cell suspensions are prepared by gentle dissociation using glass slides. Debris is separated from cells by filtration and cell suspensions are centrifuged at 250 x g for 5 min. Cells are seeded in a volume of 100 µl in 96-well plates. Mitogens were added in a volume of 10 µl at final concentrations of 25 µg/ml for LPS and 5 µg/ml for PHA, and then the cells were incubated in 5% CO2 at 37°C for 3 days. The cells were harvested onto filter strips using a harvester and [3 H]-thymidine incorporation was determined by liquid scintillation. For mitogen-induced lymphocyte proliferation assays after DMBA treatment in vitro, cell preparations from untreated mice were simultaneously exposed to mitogen (LPS) and DMBA.
In Vivo
In vivo

The metabolic activation of DMBA in the spleen plays a key role in the splenic immunotoxicity, mEH-null mice are more resistant to DMBA-induced cytotoxicity as well as immunosuppression.[1]
Animal Research Animal Models mEH-null mice

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
