Gel documentation systems or gel imaging systems could be defined as a package of instruments used to record and measure nucleic acid and protein in various types of media such as cellulose, acrylamide, and agarose. These systems come in a variety of configurations depending on the desired application and sample type. A typical gel documentation system consists of a camera with lenses of variable detection power, imaging filters, overhead illuminator, passage of light, which illuminates the gel placed on an adjustable stage and an additional transilluminator which enables collection of light. Through the use of chemiluminescence and fluorescence, gel documentation systems are deployed for various applications is hospitals, diagnostic centers, and research institutions.
