GelGreen is considered a safer alternative to ethidium bromide (EtBr), as it offers several advantages:

• Fluorescence: GelGreen is a fluorescent dye that interacts with nucleic acids and emits fluorescence when exposed to a source of ultraviolet (UV) or blue light. This fluorescence allows nucleic acids separated in a gel to be visualised and photographed.
• ​​​Safety: GelGreen is considered safer than ethidium bromide. Sensitivity: It is often used to detect relatively small amounts of DNA or RNA, making it a popular choice for molecular biology research.
• Applications: GelGreen is commonly used in techniques such as gel electrophoresis, PCR (polymerase chain reaction), DNA sequencing and other applications where visualisation of nucleic acids is required.
• Method of use: It is usually added to the gel prior to electrophoresis or to the migration buffer to obtain an appropriate concentration of dye.
