5(6)-TAMRA NHS Ester,150408-83-6
TAMRA是在用的多种不同共轭物中的荧光试剂之一，可标记蛋白质和寡核苷酸。TAMRA具有吸光的性质，它的光谱与几类常用的荧光化合物重叠，TMR是明亮的橙色荧光基团。经常用于淬灭基团的标记。 5-(6）-TAMRA是由两个不同羧基TMR单体形成的混合物 。它用来修饰氨基和羧基基团，通过EDC介导的偶联作用。它能够与胺反应衍生形成5（6）-TAMRA SE。TAMRA具有更强的光稳定性、更高的荧光产量和更低的pH敏感性。
TAMRA Acid (5(6)-Carboxytetramethylrhodamine) is one of the fluorophores most often used for preparing peptide, protein, nucleotide and nucleic acid conjugates, especially fluorescent antibodies and avidin derivatives used in immunochemistry. The absorbance and emission maxima of TAMRA conjugates are 553 nm and 575 nm respectively.
