TAMRA maleimide, 6-isomer（Cat No.:I036991）is a fluorescent labeling reagent commonly used in bioconjugation and molecular biology applications. It consists of the TAMRA (tetramethylrhodamine) fluorophore attached to a maleimide group, which allows for selective covalent bonding with thiol groups on proteins, peptides, or other biomolecules. The 6-isomer refers to the specific position of the maleimide group on the TAMRA structure. This compound is utilized for fluorescence-based assays, including protein detection, tracking, and imaging. Its bright red fluorescence and high stability make it valuable in research involving cellular dynamics, protein interactions, and diagnostic applications.
