6-TMARA C2 maleimide

Tetramethylrhodamine-6 C2 maleimide is a good alternative to tetramethylrhodamine-6-maleimide andis a single isomer. Although tetramethylrhodamine (TMR) maleimides and iodoacetamides are popular thiol-reactive labeling reagents, they are quite unstable in water, and the commercial tetramethylrhodamine maleimides and iodoacetamides often have lower purities than other tetramethylrhodamine labeling reagents (such as TAMRA SE reagents) due to their synthetic difficulties. In addition, the labeling efficiency of tetramethylrhodamine maleimides and iodoacetamides is often lower compared to that of other tetramethylrhodamine labeling dyes. TMR C2 maleimides are proven to be superior replacements to tetramethylrhodamine maleimides and iodoacetamides. These reagents react with thiol compounds, such as amino acids, peptides and proteins, to give bright red fluorescent conjugates that are extremely stable. Compared to tetramethylrhodamine maleimides and iodoacetamides, TMR C2 maleimides have hig
