Bioactivity

• Cell Research:
  Instructions 1. Solution configuration 1. Mother liquor configuration: Dissolve Methyl Blue in an appropriate solvent (such as water or PBS), usually at a concentration of 1-10mM. 2. Configuration of working liquid: When using, dilute the mother liquid with PBS/H2O/DMEM to a working liquid of a certain concentration, and dilute it according to the actual situation, such as 5μM. 1. Antibacterial staining Experimental steps: 1. Prepare the sample: Apply the bacteria or microorganism sample to be stained onto the slide, and then air-dry and fix it (such as using methanol). 2. Staining: Add Methyl Blue solution dropwise to the sample, and the staining time is usually 5-10 minutes. 3. Clean and observe: Use distilled water to clean the sample to remove excess dye. Use a microscope to observe the staining effect of bacteria or microorganisms. 2. Histological staining Experimental steps: 1. Staining sections: Immerse the tissue sections in Methyl Blue working fluid, the staining time is 5-15 minutes, and the specific time is adjusted according to the tissue type and staining intensity. 2. Clean and seal: Wash the sections with water or PBS to remove unbound dye. After the tablets were sealed with a mounting medium, use a microscope to observe the staining effect. III. Research on photodegradation of catalysts Experimental steps: 1. Reaction mixture: Mix the Methyl Blue working liquid with a catalyst (such as a photocatalyst or photosensitization catalyst). 2. Light reaction: Under light conditions (such as ultraviolet light or visible light irradiation), let the reaction mixture react for a certain period of time (usually 30 minutes to several hours). 3. Analyze the degradation effect: Use a spectrophotometer or high-performance liquid chromatography (HPLC) to monitor the photodegradation of Methyl Blue to evaluate the degradation effect of the catalyst.
