生物活性
Tetramethylrhodamine-5-iodoacetamide (5-TMRIA) 是一種選擇性巰基反應染料，用于通過半胱氨酸殘基對蛋白質進行非特異性標記。Tetramethylrhodamine-5-iodoacetamide (5-TMRIA) 可用于共價標記 DNA 片段。體外研究
Tetramethylrhodamine-5-iodoacetamide (0.5, 1.0, 2.0, 3.0, 4.0, 5.0, and 7.5 mM dye) shows different results for labeling carbonic anhydrase and myoglobin. At lower dye concentrations (up to 40:1 dye:thiol ratio) fluorescence labeling of only the carbonic anhydrase band is observed. However,as concentration increases, fluorescence labeling of both carbonic anhydrase and the lower myoglobin band is observed, indicating nonspecific labeling at these dye:thiol ratios.
