A digital gel photography system is used in molecular biology and biotechnology laboratories to capture high-resolution images of DNA, RNA, and protein gels to visualize and analyze the results of gel electrophoresis. Digital gel photography systems are an integral part of documenting and analyzing experimental outcomes such as DNA fragment patterns, protein bands, or RNA expression levels. When comparing models of gel image capture systems, ensure that the light output wavelengths match your laboratory needs as models are available with single or multiple wavelengths across the light spectrum. Also for publication-quality images, compare the resolution of gel photography systems as this can directly impact the image quality. The viewing surface or field of view should also be considered to ensure the instrument is compatible with your gel size.
