In molecular biology and biochemistry, electrophoresis is a cornerstone technique for separating and analyzing nucleic acids and proteins. Essential to the efficient execution of these methods is the use of tracking dyes, which provide visual confirmation of sample migration through the gel. Cresol Red (CAS 1733-12-6) is a well-established and highly useful tracking dye, and as a leading manufacturer and supplier in China, we are proud to offer high-quality Cresol Red to support your research needs.

Cresol Red, a synthetic triarylmethane dye, functions effectively as a tracking dye in various types of electrophoresis, including DNA, RNA, and protein separations. Unlike DNA ladders which are themselves the subject of analysis, tracking dyes are inert with respect to the separation process but are visible to the naked eye. Cresol Red provides a distinct color marker that moves through the gel matrix, allowing researchers to monitor the progress of the electrophoresis run in real-time. This visual feedback is crucial for determining the optimal time to terminate the experiment, preventing the over-separation or loss of analytes. Its migration characteristics are well-understood, making it a predictable component of electrophoresis protocols.

When used in agarose gels for DNA or RNA electrophoresis, Cresol Red typically migrates with an apparent molecular size comparable to that of a 125 bp DNA fragment. This makes it a convenient marker for estimating the migration front, especially when working with smaller DNA fragments. Importantly, Cresol Red has been shown not to inhibit common enzymatic reactions like Taq polymerase activity, meaning its presence in a sample will not interfere with downstream applications such as PCR. This compatibility is a significant advantage for researchers performing sequential experimental steps.
