Gel Imaging System

Home > Bio Lab Equipment > Gel Imaging System

Gel imaging system or gel documenting system is a method popularly used in molecular biology laboratories to image and document nucleic acid and protein polyacrylamide or agarose gels, especially those stained with ethidium bromide or other fluorophores such as SYBR Green. The method employs a sophisticated device called Gel Doc, that consists of an ultraviolet (UV) light transilluminator, a hood to shield external light sources and a camera for image capturing. The gel is placed on the transilluminator with the camera directly above it. Normally the camera is operated by computing technology so that the image is precision adjusted before capturing.
