After completing electrophoresis, it is crucial to examine the DNA bands' results. The transilluminator device offers a straightforward and high-quality way to visualize these DNA bands. To address the needs of researchers and specialists, Denagene Tajhiz has developed various models of transilluminators, particularly UV transilluminators, which are extensively used for detecting DNA and RNA bands. By attaching fluorescent dyes to specific DNA bands, these dyes enable the detection of DNA bands under particular UV light wavelengths. To ensure user safety from harmful UV radiation, all UV transilluminator models by Denagene Tajhiz feature a stainless-steel housing cover.
