- A gel doc, also known as a gel documentation system, gel image system or gel imager, refers to equipment widely used in molecular biology laboratories for the imaging and documentation of nucleic acid and protein suspended within polyacrylamide or agarose gels. These gels are typically stained with ethidium bromide or other nucleic acid stains such as GelGreen. Generally, a gel doc includes an ultraviolet (UV) light transilluminator, a hood or a darkroom to shield external light sources and protect the user from UV exposure, and a CCD camera for image capturing. With advancement in CMOS camera sensors like Sony's Pregius and Exmor series, low light capable cameras made of these sensors are also being incorporated in gel documentation systems The main manufacturers of gel documentation systems are Cytiva, Bio Rad, , Bioolympics, Syngene, Vilber Lourmat, UVItec, UVP, Biozen, Imagene and Aplegen. Recently affordable systems from Chinese manufacturers like Clinx and Indian manufacturers like iGene Labserve , Biozen Labs have entered the market. For certain extremely low light applications like chemiluminescence, gel documentation systems are also being designed with cooled cameras that enable longer exposures without the sensor heating up. These chemi doc systems are very sensitive, have low noise and produce images of faint bands and spots in gels and blots that would otherwise not have been visible to the naked eye. Models also include features to handle a variety of fluorescence and chemiluminescence with cameras cooled to -28 to -60 °C. Other advanced features include instant printing on-board the camera and Wi-Fi connectivity for control by smartphone and tablet devices. (en)
