Biological Activity

Description Crystal violet(Gentian Violet) is a triarylmethane dye.
In vitro
In vitro

1.Preparation of MitoSOX Red working solution
Dilute the 2 g Crystal Violet in 20 mL 95% ethanol andmixed with 80 ml 1% ammonium oxalate solution solution for 24 h to obtain working solution.
2.Sample processing
2.1 Paraffin section:
First dewaxing with xylene for 5-10 min, then with fresh xylene, then dewaxing with 100% ethanol for 5 min after dewaxing for 5-10 min. Then 90% ethanol was used for 2 min. At last, 70% ethanol was used for 2 min. DDH2O 2 min.
2.2 Frozen section:
distilled water for 2 min.
2.3 Tissue culture cells:
fixed with 4% paraformaldehyde for more than 10 min. Wash with distilled water for 2 min, replace with fresh distilled water, and wash again for 2 min.
Note: Other fixatives can be selected according to specific experiments.
3.Crystal violet staining
3.1 After the sample to be tested is treated with the above method, the crystal violet dyeing solution is directly added and dyed for 10 minutes at room temperature (the dyeing solution needs to cover the sample, and the specific dyeing time can be adjusted according to the required dyeing results).
3.2 Wash well in distilled water.
3.3 Dry at room temperature.
3.4 Observe and photograph by light microscope.

Working concentration: mg/ml;

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.
