TAMRA-PEG4-NHS ester（Cat No.:I036992）is a bioconjugation reagent that combines the fluorescent dye TAMRA (Tetramethylrhodamine) with a polyethylene glycol (PEG) linker and an N-hydroxysuccinimide (NHS) ester. The NHS ester allows for efficient coupling with primary amines on biomolecules, such as proteins or peptides, facilitating the creation of fluorescently labeled conjugates. The PEG4 linker enhances solubility and stability, while TAMRA provides strong fluorescence for use in imaging, tracking, or analytical applications. This compound is useful in research involving protein labeling, flow cytometry, microscopy, and other bioanalytical techniques.
