Tetramethylrhodamine-5-maleimide
Based on 1 Customer Validation
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.
