Introduction of 174568-67-3 :

Tetramethylrhodamine-5-maleimide is a fluorescent probe with high specificity for cysteine thiol (SH) groups. Tetramethylrhodamine-5-maleimide has high sensitivity, responds rapidly to negatively charged nanoparticles, and shows a concentration-dependent decrease in fluorescence intensity, but it is susceptible to interference from humic acids[1]. In Vitro:Tetramethylrhodamine-5-maleimide (50 mM; 2 h) covalently labels the custom-engineered Ac-KKKKKKKGGGC-OH peptide with 100% efficiency under the specified conditions, yielding a purified labeled peptide with a purity of >90%[1].
