| pH range of acid-base indicator discoloration | Yellow (0.1) to greenish-blue (2.3) |
| Biological applications | |
| methyl green-panning reaction | the phosphate groups of DNA and RNA make both easy to bind to basic dyes. Both methyl green and peyronin are basic dyes, but under suitable conditions, methyl green has a specific affinity for high Poly DNA, and peyronin can stain RNA, but the specificity is poor. Therefore, treating tissue sections with a mixture of Methyl green and peyronin at a pH of about 4.8 (the effect is better with Karot's or sinker's fixative) can cause DNA and RNA to be stained green and red, respectively, the exact mechanism is not clear, only the binding ability of Methyl green to DNA is related to the integrity of the double helix space configuration of DNA molecule. For example, RNA is extracted with 1% NaCl or ribonuclease, and then methyl green-panning reaction is carried out, and as a result, the presence of RNA in the cell can be confirmed. |
| artificial dyes | that is aniline dyes or coal tar dyes, many kinds, a wide range of applications. Its disadvantage is that it is easy to fade by sunlight, aniline blue, bright green, methyl green and so on. In the production of attention to grasp the pH, and to avoid direct sunlight, but also after several years does not fade. methyl green is a basic dye. It is green powder, soluble in water (solubility 8%) and alcohol (solubility 3%). Methyl green is the most valuable cell and stain, cytology is commonly used to stain the cytoplasm, with acid fuchsin can be used for plant xylem staining. |
| Use | for bacterial staining (fresh specimen nuclei staining) methyl green-hydrochloric acid mixture for sperm, neisseria gonorrhoeae and mast cell staining. nuclear stain, bacterial stain (fresh specimen, nuclear stain). The methyl green-hydrochloric acid mixture was used to assay sperm, chromatin staining, Neisseria gonorrhoeae and mast cell staining. |
