5(6)-Rhodamine Green X NHS ester

Rhodamine green is 5(6)-carbonylated rhodamine 110. Rhodamine Green has excellent optical properties, good light stability, very bright fluorescence brightness and is insensitive to pH between pH 4-9. The fluorescence spectrum of rhodamine green is very close to that of fluorescein, Oregon green and FITC, and the extinction coefficient is similar to the quantum yield, but the photostability and pH stability are much better, so it is a perfect substitute for them. NHS activated ester (N-hydroxysuccinimide ester, successful ester, Se) is the most commonly used activated group in biomarker reaction. It activates the carboxyl group in the dye molecule so that it can react with the amine group (main primary amine) on the target biomolecule to form a stable amide bond. In addition, the labeling dye contains a long arm with a seven atom spacer (x), which can improve the labeling efficiency and reduce the influence of the labeling object on the dye molecules to a certain extent.
