5（6）-TAMRA-C5- maleimide是硫醇反应性罗丹明染料。当染料与蛋白质结合时，染料和马来酰亚胺反应性基团之间的C5间隔臂增强了染料的荧光。当pH控制在7左右时，分子中的胺被质子化而不具有活性，所以马来酰亚胺可以选择性地标记硫醇类物质。 染料是5-和6-异构体的混合物，其适用于蛋白质标记，或标记其他大分子。 产品参数： 外观：可溶于DMSO或DMF的红色固体 Ex/Em：540/565 nm (MeOH) 分子式：C34H34N4O6 分子量：594.7 注意事项： 1. 荧光染料均存在淬灭，请注意避光，以减缓荧光淬灭。 2. 为了您的安全和健康，请穿实验服并戴一次性手套操作。 应用范围： 偶联硫醇 Product introduction： 5 (6) - tamra-c5-maleimide is a thiol reactive rhodamine dye. When the dye binds to the protein, the C5 spacer arm between the dye and the maleimide reactive group enhances the fluorescence of the dye. When the pH is controlled at about 7, the amine in the molecule is protonated without activity, so maleimide can selectively label thiols. Dyes are mixtures of 5- and 6-isomers, which are suitable for protein labeling, or labeling other macromolecules. Product parameters： Appearance: red solid soluble in DMSO or DMF ex/em:540/565 nm (MeOH) molecular formula: c34h34n4o6 molecular weight: 594.7 Matters needing attention： 1. fluorescent dyes are quenched. Please avoid light to slow down fluorescence quenching. 2. for your safety and health, please wear experimental clothes and disposable gloves. Scope of application： Coupling thiols
