CAS 91809-66-4: 5-Carboxytetramethylrhodamine

Description: 5-Carboxytetramethylrhodamine (often abbreviated as TMR or TMR-C) is a fluorescent dye belonging to the rhodamine family, characterized by its vibrant red fluorescence. It is commonly used in various biological and chemical applications, particularly in fluorescence microscopy and flow cytometry due to its high quantum yield and photostability. The presence of a carboxylic acid group enhances its solubility in aqueous solutions, making it suitable for labeling biomolecules such as proteins and nucleic acids. The dye exhibits strong absorption in the green region of the spectrum and emits light in the red region, allowing for effective separation from other fluorescent markers. Additionally, its ability to form conjugates with amines and other reactive groups makes it versatile for various labeling techniques. Overall, 5-Carboxytetramethylrhodamine is a valuable tool in molecular biology and biochemistry for tracking and visualizing cellular processes.
