5(6)-Rhodamine Green amine 

Rhodamine green, which is 5(6)-carbonylated rhodamine 110, is the precursor of Alexa fluor 488 (af488) before sulfonation. 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.The product contains amino functional groups and can react with functional groups such as carboxylic acid. 6 carbon short chain helps to separate dye molecules from labeled objects, improve labeling efficiency and reduce the impact of labeled objects on dye molecules.
