Understanding Transilluminators
Transilluminators are essential laboratory devices used primarily in molecular biology and biochemistry for visualising nucleic acids, proteins, and other biomolecules that have been separated using gel electrophoresis. These instruments utilise ultraviolet (UV) or blue light to illuminate gels, allowing researchers to observe bands of DNA, RNA, or proteins that are stained with specific dyes, such as ethidium bromide or SYBR Safe. Transilluminators come in various sizes and configurations, including models with adjustable wavelength settings to accommodate different types of gels and stains. Many modern transilluminators also feature integrated imaging systems that enable researchers to capture high-resolution images for documentation and analysis. By providing clear visibility of gel contents, transilluminators play a crucial role in experimental analysis, quality control, and genetic research.
