Industrial Applications of Ethidium bromide
| Industry | Application | Process |
|---|---|---|
| Molecular Biology | Nucleic acid stain | Used for DNA/RNA visualization in gel electrophoresis |
| Biomedical | Fluorescent labeling and detection | Exhibits fluorescence under UV light upon binding to nucleic acids |
| Research Laboratories | Cell viability and apoptosis studies | Applied as a dead-cell dye to distinguish viable from non-viable cells |
| Genetics | Chromosome structure analysis | Used in chromosome banding and fluorescence in situ hybridization (FISH) |
Manufacturing Quality Control of Ethidium bromide
| Test Item | Common Testing Methods | Method Overview |
|---|---|---|
| Appearance | Visual Inspection | Observe whether the sample is a reddish-brown or dark red crystalline powder; it should be dry, free of caking, and devoid of visible impurities. |
| Solubility | Solubility Test | Dissolve an appropriate amount of sample in water or methanol; it should dissolve completely, forming an orange-red, clear, and transparent solution without suspended particles or precipitate. |
| UV-Visible Absorption Spectrum | UV-Vis Spectrophotometry | Prepare a solution of a specified concentration and measure the maximum absorption peaks near 260 nm and 302 nm to confirm compliance with the standard spectral profile. |
| Assay | UV Spectrophotometry / HPLC | Determine absorbance at a specific wavelength (e.g., approximately 480 nm) using UV spectrophotometry, or quantify the main component content using HPLC with an external standard method; content should be within 98%–102%. |
| Related Substances (Impurities) | High-Performance Liquid Chromatography (HPLC) | Use reversed-phase HPLC to detect possible synthetic by-products or degradation products, and calculate the total impurity level to ensure compliance with specified limits. |
| Water Content | Karl Fischer Titration | Determine the water content of the sample; typically required to be ≤5.0% to ensure stability and storage performance. |
| Residue on Ignition | Residue on Ignition Test | After high-temperature incineration, weigh the residual residue to assess the level of inorganic impurities; generally required to be ≤0.5%. |
| Microbial Limits | Microbial Limit Test | Perform microbial limit testing according to pharmacopoeial methods to determine total counts of bacteria, molds, and yeasts, controlling microbial contamination for reagent-grade product quality control. |
