A gel photo documentation system is a composite system used to observe, take photos and analyze the bands of the gels obtained from electrophoretic runs. These systems are designed to allow clear, high-quality images to be obtained, offering better analysis, and providing a results backup system, which is essential when publishing the results of an investigation.
These equipments allow the reading of the results in a fast and precise way, they reduce the probabilities of human error when analyzing and quantifying the results, because it allows us to observe those bands that are not observed with the naked eye, such as those observed by fluorescence, thanks to the presence of a series of specialized elements that allow the image to be captured.
Electrophoresis is one of the main molecular biology techniques, they are considered the most used technique in laboratories in everything related to nucleic acid research. Using electrophoresis, we can separate DNA and RNA fragments based on their size and electrical charge through their migration through a porous material (gel), visualize them by means of a staining, many of them based on fluorescence, such as ethidium bromide. , and determine the content of nucleic acids or proteins in a sample, thus having an estimate of their concentration.
