Gel documentation systems, also known as gel imagers or gel doc systems, are specialized instruments used to capture, visualize, and analyze electrophoresis gels in molecular biology and biochemistry workflows. These systems are essential for documenting results from DNA, RNA, and protein electrophoresis and are widely used in academic laboratories, biotechnology companies, clinical diagnostics, and educational settings.
Gel doc systems typically image gels stained with intercalating dyes such as ethidium bromide, SYBR Safe, GelRed, or Coomassie Blue. These dyes fluoresce under UV or blue light, and the emitted signal is captured by a high-resolution CCD or CMOS camera, enabling precise visualization of nucleic acid fragments or protein bands.
Common applications include PCR product validation, restriction digest analysis, DNA/RNA quantification, protein purity assessment, and Western blot imaging. Many systems support both fluorescent and chemiluminescent detection modes, offering versatility across molecular biology protocols.
Modern gel documentation systems often feature automated exposure controls, integrated transilluminators (UV, blue, or white light), touchscreen interfaces, and analysis software capable of band quantification, molecular weight estimation, and densitometry. Some models are designed to be compatible with gel-safe dyes and include light shielding for user safety.
