5-Carboxyrhodamine 110 NHS ester 是 BP Fluor 488 染料的非磺化类似物。胺反应性 5(6)-羧基罗丹明 110 NHS 酯可用于产生明亮且光稳定的绿色荧光生物共轭物，其激发/发射最大值约为 502/527 nm。对于许多应用而言，该染料优于 5-(6)-羧基荧光素 NHS 酯或 FITC，因为它具有出色的光稳定性和对 pH（4-9）的荧光不敏感性。尽管羧基罗丹明 110 NHS 酯的混合异构体是首选，常规用于标记蛋白质、肽和核苷酸的荧光染料，但用 5(6) 异构体标记的肽和核苷酸的纯化可能会很麻烦，因为在 HPLC 纯化中信号会明显增宽。用单一异构体标记的肽和核苷酸通常在结合过程中经常需要的 HPLC 纯化中提供更好的分辨率。

生物活性

5-Carboxyrhodamine 110 NHS Ester is the nonsulfonated analog of the BP Fluor 488 dye. The amine-reactive 5(6)-Carboxyrhodamine 110 NHS Ester can be used to create bright and photostable green-fluorescent bioconjugates with excitation/emission maxima ~502/527 nm. For many applications, the dye is preferred over 5-(6)-carboxyfluorescein NHS ester or FITC because of its exceptional photostability and fluorescence insensitivity to pH (4-9). Although the mixed isomers of Carboxyrhodamine 110 NHS Ester preferred, routinely used fluorescent dye for labeling proteins, peptides and nucleotides, purification of peptide and nucleotides labeled with 5(6) isomers might be troublesome due to significant signal broadening in HPLC purification. Peptides and nucleotides labeled with a single isomer usually give better resolution in HPLC purification that is often required in the conjugation processes.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
