Sulfo Rhodamine Methanethiosulfonate (Cat No.:R000436) is a fluorescent dye used in biochemical research to label and track proteins. It contains a sulfhydryl-reactive methanethiosulfonate group, which forms a covalent bond with cysteine residues in proteins. This labeling allows researchers to study protein structure, function, and localization. MTS-Rhodamine is particularly useful in fluorescence microscopy and flow cytometry experiments. Its bright fluorescence and high photostability make it a valuable tool for visualizing and analyzing proteins in biological samples.
