GEL-Doc

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.^[1] 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
