NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing researchers with the highest quality chemical intermediates to drive scientific discovery. Among our comprehensive catalog, fluorescent dyes play a pivotal role in advancing fields such as molecular biology, diagnostics, and drug development. In particular, the purity of these dyes directly impacts the reliability and reproducibility of experimental outcomes, making high-purity fluorescent dyes indispensable tools for modern biological research.

One such critical compound is 5-Carboxytetramethylrhodamine, also known as 5-TAMRA. This rhodamine derivative is a powerful fluorescent probe extensively used for labeling biomolecules like peptides and proteins. The significance of its high purity, typically specified at 97% minimum, cannot be overstated. For researchers conducting complex biological applications, the subtle differences between positional isomers of a dye can lead to significant variations in conjugation efficiency, photophysical properties, and ultimately, the biological activity of the labeled molecule. By opting for a purified single isomer like 5-Carboxytetramethylrhodamine, scientists can minimize these variables, ensuring greater consistency and accuracy in their findings.

The application of 5-carboxytetramethylrhodamine for peptide labeling is widespread. Fluorescently tagged peptides are instrumental in various assays, including drug delivery studies, receptor binding experiments, and enzyme activity monitoring. The ability to precisely track and quantify these labeled peptides is crucial for understanding biological processes. Similarly, in protein conjugation, the dye is attached to proteins to create fluorescently labeled antibodies, enzymes, or other protein-based reagents used in techniques like ELISA, Western blotting, and fluorescence microscopy. The inherent brightness and photostability of the rhodamine scaffold, combined with the precise labeling facilitated by 5-TAMRA, make it a preferred choice.

For those looking to buy this essential reagent, understanding its chemical properties, such as its CAS number 91809-66-4 and molecular formula C25H22N2O5, is important.
