Gel Doc

Updated: Apr 14, 2021


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 CMOS camera for image capturing. This project was initiated by the Department of Bio Technology, SRCAS. The technical support for the project was given by me and my colleague Subash.




With a mini computer running inside, this device is operated with a 7" touch display. This device uses a 5 MP camera for Image capturing and Image processing. The testing was done with Flurocein in order to simplify the process. The below photos are output taken from the device.

Most of the works in this project were confidential and hence sharing the information is limited.
