MCE 国际站：Crystal Violet

产品活性：Crystal Violet，也称为龙胆紫、甲基紫 10B，是一种三苯甲烷类染料，碱性染料，可以和细胞核中的 DNA 结合，从而将细胞核染为深紫色。常用于革兰氏染色来进行细菌分类，或者用于细胞或组织学染色。

研究领域：Others  |  Anti-infection

作用靶点：Fluorescent Dye  |  Influenza Virus  |  Bacterial

In Vitro: General Protocol

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.

Storage
